ICD-10: D17.71

Benign lipomatous neoplasm of kidney

Additional Information

Description

Benign lipomatous neoplasms of the kidney, classified under ICD-10 code D17.71, represent a specific type of tumor characterized by the proliferation of adipose (fat) tissue within the renal area. Here’s a detailed overview of this condition, including its clinical description, diagnostic criteria, and relevant considerations.

Clinical Description

Definition

A benign lipomatous neoplasm of the kidney is a non-cancerous tumor composed primarily of mature adipocytes (fat cells). These tumors are generally asymptomatic and are often discovered incidentally during imaging studies conducted for other reasons.

Epidemiology

While benign lipomatous neoplasms can occur in various organs, their occurrence in the kidney is relatively rare. They are more commonly found in adults and can be associated with obesity or metabolic disorders, although the exact etiology remains unclear.

Symptoms

Most patients with a benign lipomatous neoplasm of the kidney do not exhibit symptoms. However, in some cases, larger tumors may lead to:
- Abdominal pain or discomfort
- Hematuria (blood in urine)
- Palpable mass in the abdomen

Diagnosis

Diagnosis typically involves imaging studies such as:
- Ultrasound: Can help identify the presence of a mass.
- CT Scan: Provides detailed images of the kidney and surrounding structures, helping to differentiate between benign and malignant lesions.
- MRI: May be used for further characterization of the tumor.

In some cases, a biopsy may be performed to confirm the diagnosis, although this is less common due to the benign nature of the tumor.

ICD-10 Code Details

Code Information

  • ICD-10 Code: D17.71
  • Category: D17 refers to benign lipomatous neoplasms, with D17.71 specifically denoting those located in the kidney.

Coding Guidelines

When coding for D17.71, it is essential to ensure that the diagnosis is confirmed through appropriate imaging or histological examination. Accurate coding is crucial for proper documentation and reimbursement processes in clinical settings.

Treatment and Management

Management Approach

Since benign lipomatous neoplasms are non-cancerous and often asymptomatic, treatment may not be necessary. However, management options include:
- Observation: Regular monitoring through imaging if the tumor is small and asymptomatic.
- Surgical Intervention: In cases where the tumor is large, symptomatic, or there is uncertainty regarding the diagnosis, surgical excision may be considered.

Prognosis

The prognosis for patients with benign lipomatous neoplasms of the kidney is generally excellent, given their benign nature. Recurrence is rare following surgical removal.

Conclusion

Benign lipomatous neoplasms of the kidney, classified under ICD-10 code D17.71, are non-cancerous tumors that typically do not require aggressive treatment. Understanding the clinical presentation, diagnostic methods, and management options is essential for healthcare providers to ensure appropriate care for affected patients. Regular follow-up and monitoring are recommended to manage any potential complications or changes in the tumor's status.

Clinical Information

Benign lipomatous neoplasms, specifically coded as D17.71 in the ICD-10 classification, refer to non-cancerous tumors composed primarily of adipose (fat) tissue located in the kidney. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and management.

Clinical Presentation

Definition and Nature

Benign lipomatous neoplasms of the kidney are characterized by the proliferation of adipose tissue within the renal parenchyma. These tumors are typically asymptomatic and are often discovered incidentally during imaging studies conducted for other reasons.

Common Imaging Findings

On imaging, particularly ultrasound, CT, or MRI, these neoplasms appear as well-defined, homogeneous masses that are usually hyperechoic (bright) on ultrasound and demonstrate fat density on CT scans. The presence of fat within the lesion is a key diagnostic feature that helps differentiate benign lipomas from malignant renal tumors.

Signs and Symptoms

Asymptomatic Nature

Most patients with a benign lipomatous neoplasm of the kidney do not exhibit symptoms. However, in some cases, the following signs and symptoms may occur:

  • Abdominal Pain: Some patients may experience vague abdominal discomfort or flank pain, particularly if the tumor is large enough to cause pressure effects on surrounding structures.
  • Hematuria: Although rare, some patients may present with blood in the urine, which could be due to irritation of the renal parenchyma or associated conditions.
  • Palpable Mass: In cases where the tumor is significantly large, a palpable mass may be detected during a physical examination.

Incidental Findings

Due to their often asymptomatic nature, these neoplasms are frequently found incidentally during imaging studies for unrelated conditions, such as kidney stones or other abdominal complaints.

Patient Characteristics

Demographics

  • Age: Benign lipomatous neoplasms can occur in adults of various ages, but they are more commonly diagnosed in middle-aged individuals.
  • Gender: There is no strong gender predisposition, although some studies suggest a slight male predominance.

Risk Factors

While specific risk factors for benign lipomatous neoplasms of the kidney are not well-defined, general factors associated with lipomatous tumors may include:
- Obesity: Increased body fat may contribute to the development of lipomatous tumors.
- Genetic Factors: Some patients may have a familial predisposition to developing multiple lipomas, although this is more commonly associated with familial multiple lipomatosis rather than isolated renal lipomas.

Conclusion

In summary, benign lipomatous neoplasms of the kidney (ICD-10 code D17.71) are typically asymptomatic and often discovered incidentally during imaging studies. While they may present with vague abdominal pain or hematuria in rare cases, most patients do not exhibit significant symptoms. Understanding the clinical presentation and patient characteristics is essential for healthcare providers to ensure accurate diagnosis and appropriate management of this benign condition. Regular monitoring may be recommended for incidental findings, especially if the neoplasm is large or symptomatic.

Approximate Synonyms

The ICD-10 code D17.71 refers specifically to a benign lipomatous neoplasm of the kidney. This condition is characterized by the presence of a lipoma, which is a benign tumor composed of adipose (fat) tissue. Below are alternative names and related terms associated with this diagnosis:

Alternative Names

  1. Benign Renal Lipoma: This term emphasizes the benign nature of the tumor located in the kidney.
  2. Lipomatous Neoplasm of the Kidney: A broader term that includes any lipoma found in the renal area.
  3. Adipose Tumor of the Kidney: This term highlights the fat composition of the tumor.
  4. Renal Lipomatous Tumor: Another variation that specifies the tumor's location in the renal system.
  1. Lipoma: A general term for a benign tumor made up of fat tissue, which can occur in various locations in the body, including the kidney.
  2. Benign Neoplasm: A broader category that includes any non-cancerous growth, of which lipomas are a specific type.
  3. Adipose Tissue Tumor: Refers to tumors that arise from adipose tissue, which includes lipomas.
  4. Neoplasm: A general term for any new and abnormal growth of tissue, which can be benign or malignant.

Clinical Context

In clinical practice, the identification of a benign lipomatous neoplasm of the kidney may involve imaging studies such as ultrasound or CT scans, which can help differentiate it from malignant tumors. The diagnosis is often confirmed through histological examination if surgical intervention is performed.

Understanding these alternative names and related terms can be crucial for healthcare professionals when documenting cases, coding for insurance purposes, or discussing patient conditions.

Diagnostic Criteria

The diagnosis of a benign lipomatous neoplasm of the kidney, classified under ICD-10 code D17.71, involves several criteria and diagnostic approaches. Below is a detailed overview of the criteria used for diagnosis, including clinical presentation, imaging studies, and histopathological evaluation.

Clinical Presentation

  1. Symptoms:
    - Many patients with benign lipomatous neoplasms may be asymptomatic. However, if symptoms do occur, they can include flank pain, hematuria (blood in urine), or a palpable mass in the abdomen or flank area[3].
    - Symptoms may arise due to the mass effect of the lipoma on surrounding structures.

  2. Patient History:
    - A thorough medical history is essential, including any previous abdominal surgeries, family history of neoplasms, and any symptoms that may suggest renal pathology.

Imaging Studies

  1. Ultrasound:
    - An abdominal ultrasound is often the first imaging modality used. It can help identify the presence of a mass in the kidney and assess its characteristics (e.g., echogenicity) to differentiate it from other types of renal masses[4].

  2. CT Scan:
    - A computed tomography (CT) scan of the abdomen is more definitive. It can provide detailed information about the size, location, and composition of the mass. Lipomas typically appear as well-defined, homogeneous masses with low attenuation on CT scans, which helps distinguish them from malignant tumors[5].

  3. MRI:
    - Magnetic resonance imaging (MRI) may be used in certain cases, particularly when there is a need to further characterize the mass or when other imaging modalities are inconclusive. Lipomas generally exhibit high signal intensity on T1-weighted images and low signal intensity on T2-weighted images[4].

Histopathological Evaluation

  1. Biopsy:
    - While not always necessary, a biopsy may be performed if there is uncertainty regarding the nature of the mass. Histological examination can confirm the diagnosis of a lipoma by demonstrating mature adipocytes (fat cells) without atypia or significant cellularity[3].

  2. Differential Diagnosis:
    - It is crucial to differentiate benign lipomatous neoplasms from other renal masses, such as renal cell carcinoma or angiomyolipoma, which may have overlapping imaging characteristics. This differentiation is often guided by imaging findings and histopathological results[5].

Conclusion

The diagnosis of a benign lipomatous neoplasm of the kidney (ICD-10 code D17.71) relies on a combination of clinical evaluation, imaging studies, and, when necessary, histopathological analysis. Understanding these criteria is essential for accurate diagnosis and appropriate management of patients presenting with renal masses. If there are any uncertainties in diagnosis, further imaging or biopsy may be warranted to ensure the correct treatment approach.

Treatment Guidelines

Benign lipomatous neoplasms, specifically those classified under ICD-10 code D17.71, refer to lipomas located in the kidney. These tumors are generally non-cancerous and often asymptomatic, which influences the treatment approach. Below is a detailed overview of the standard treatment strategies for this condition.

Understanding Benign Lipomatous Neoplasms

What is a Lipoma?

A lipoma is a benign tumor composed of adipose (fat) tissue. They can occur in various locations throughout the body, including the kidneys. While most lipomas are harmless and do not require treatment, their presence in the kidney can sometimes lead to complications or symptoms that necessitate intervention[1].

Symptoms and Diagnosis

Many patients with a renal lipoma may remain asymptomatic, and these tumors are often discovered incidentally during imaging studies for unrelated issues. When symptoms do occur, they may include:
- Abdominal pain
- Hematuria (blood in urine)
- Urinary obstruction

Diagnosis typically involves imaging techniques such as ultrasound, CT scans, or MRI, which help differentiate lipomas from other renal masses[1][2].

Treatment Approaches

Observation

For asymptomatic lipomas, particularly those that are small and not causing any complications, a conservative approach of observation is often recommended. Regular follow-up imaging may be advised to monitor the size and characteristics of the lipoma over time[1][2].

Surgical Intervention

Surgical treatment may be indicated in the following scenarios:
- Symptomatic Lipomas: If the lipoma causes significant symptoms, such as pain or obstruction, surgical removal may be necessary.
- Large Lipomas: Larger tumors that could potentially lead to complications or are difficult to monitor may also warrant surgical excision.
- Uncertain Diagnosis: If imaging studies do not definitively identify the mass as a lipoma, surgical intervention may be required to obtain a biopsy and rule out malignancy[1][2].

Surgical Techniques

The surgical approach can vary based on the size and location of the lipoma:
- Laparoscopic Surgery: Minimally invasive techniques are often preferred for their reduced recovery time and lower complication rates.
- Open Surgery: In cases where the lipoma is large or located in a challenging area, open surgical techniques may be necessary[1].

Postoperative Care

Post-surgery, patients typically require monitoring for complications such as infection or bleeding. Follow-up imaging may also be performed to ensure complete removal of the lipoma and to check for recurrence[1][2].

Conclusion

The management of benign lipomatous neoplasms of the kidney (ICD-10 code D17.71) primarily hinges on the presence of symptoms and the size of the tumor. While many cases can be managed conservatively with observation, surgical intervention is warranted in symptomatic or large tumors. Regular follow-up is essential to monitor for any changes in the condition. If you suspect you have a renal lipoma or are experiencing related symptoms, consulting a healthcare professional for personalized advice and treatment options is crucial.
