ICD-10: A21.0

Ulceroglandular tularemia, classified under ICD-10 code A21.0, is a specific form of tularemia, a zoonotic infection caused by the bacterium Francisella tularensis. This condition is characterized by a combination of ulcerative skin lesions and lymphadenopathy, typically following exposure to infected animals or contaminated environments.

Clinical Description

Etiology

Ulceroglandular tularemia is primarily caused by Francisella tularensis, which can be transmitted to humans through various routes, including:
- Direct contact with infected animals, particularly rabbits and rodents.
- Insect bites, especially from ticks and deer flies.
- Inhalation of contaminated aerosols or dust.
- Ingestion of contaminated food or water.

Symptoms

The clinical presentation of ulceroglandular tularemia typically includes:
- Fever: Often the first symptom, which can be high and accompanied by chills.
- Ulcerative Lesions: A characteristic skin ulcer develops at the site of infection, often accompanied by a necrotic center and raised edges.
- Lymphadenopathy: Swelling of regional lymph nodes, which may become painful and tender.
- Systemic Symptoms: Patients may experience malaise, headache, and muscle aches.

Diagnosis

Diagnosis of ulceroglandular tularemia is based on:
- Clinical Presentation: Recognition of the characteristic ulcer and lymphadenopathy.
- Laboratory Tests: Serological tests, culture of the organism, or PCR can confirm the diagnosis. However, culture is often challenging due to the fastidious nature of the bacterium.

Differential Diagnosis

Ulceroglandular tularemia must be differentiated from other conditions that can cause similar symptoms, such as:
- Cutaneous anthrax
- Cat scratch fever
- Other infectious causes of lymphadenopathy

Treatment

The treatment for ulceroglandular tularemia typically involves:
- Antibiotics: First-line treatments include streptomycin or gentamicin. Doxycycline and ciprofloxacin are alternatives, especially in cases of mild disease or for patients who cannot tolerate aminoglycosides.
- Supportive Care: Management of symptoms and supportive care for fever and pain.

Prognosis

With appropriate antibiotic treatment, the prognosis for ulceroglandular tularemia is generally good, although severe cases can lead to complications if not treated promptly. The condition is not typically fatal, but it can cause significant morbidity.

Ulceroglandular tularemia, classified under ICD-10 code A21.0, is a zoonotic infection caused by the bacterium Francisella tularensis. This condition is characterized by the development of ulcers and swollen lymph nodes, typically following exposure to infected animals or contaminated environments. Diagnosing ulceroglandular tularemia involves a combination of clinical evaluation, patient history, and laboratory testing. Below are the key criteria used for diagnosis:

Clinical Presentation

1. Symptoms: Patients often present with fever, chills, headache, and fatigue. The hallmark of ulceroglandular tularemia is the presence of a painful ulcer at the site of infection, usually accompanied by swollen lymph nodes (lymphadenopathy) near the ulcer[1].

2. Ulcer Characteristics: The ulcer typically appears as a painful, necrotic lesion with a characteristic base, which may be surrounded by erythema. The size and depth of the ulcer can vary, but it is often well-defined[1].

3. Lymphadenopathy: Swollen lymph nodes, particularly in the region draining the ulcer, are a significant indicator of the disease. These nodes may be tender and can become suppurative (filled with pus) in some cases[1].

Exposure History

1. Risk Factors: A detailed patient history is crucial. Exposure to potential sources of Francisella tularensis, such as handling infected animals (especially rabbits), bites from infected insects, or contact with contaminated water or soil, should be assessed[1].

2. Geographical Considerations: The incidence of tularemia can vary by region, with certain areas having higher prevalence rates. Knowledge of local epidemiology can aid in diagnosis[1].

Laboratory Testing

1. Serological Tests: Serological assays can detect antibodies against Francisella tularensis. However, these tests may take time to yield results and are not always definitive in the acute phase of the disease[1].

2. Culture and PCR: Isolation of the bacterium from clinical specimens (such as ulcer swabs or lymph node aspirates) is the gold standard for diagnosis. However, Francisella tularensis is a biosafety level 3 pathogen, and cultures should be performed in specialized laboratories. Polymerase chain reaction (PCR) testing can also be utilized for rapid detection of the pathogen in clinical samples[1].

3. Histopathological Examination: Biopsy of the ulcer may reveal characteristic findings, such as necrotizing granulomatous inflammation, which can support the diagnosis[1].

Differential Diagnosis

It is essential to differentiate ulceroglandular tularemia from other conditions that may present similarly, such as:

• Cutaneous anthrax
• Herpes simplex virus infections
• Other bacterial skin infections
• Lymphogranuloma venereum

A thorough clinical evaluation and appropriate laboratory tests are necessary to rule out these conditions[1].

Conclusion

Diagnosing ulceroglandular tularemia (ICD-10 code A21.0) requires a comprehensive approach that includes clinical assessment, patient history, and laboratory confirmation. Awareness of the disease's clinical features and potential exposure risks is vital for timely diagnosis and treatment. If you suspect ulceroglandular tularemia, it is crucial to consult healthcare professionals for appropriate testing and management.
