Oral tuberculosis lesions typically present with all of the following findings except_______________?
Show answer Hide answer
Answer: B. Hyaline degeneration
Explanation
Oral tuberculosis lesions feature caseating granulomas rather than hyaline degeneration. Histology demonstrates epithelioid histiocytes, Langhans giant cells, and central caseation. Mycobacterium tuberculosis infection induces a characteristic chronic granulomatous inflammatory response. Primary oral tuberculosis is rare and typically presents as a painful chronic ulcer. Acid-fast bacilli stains help visualize the causative bacteria within biopsy specimens. Lungs represent the primary infection site with secondary spread to oral mucosa.
Prompt multidrug antitubercular therapy ensures complete resolution of oral lesions. Clinicians must wear proper personal protective equipment during diagnostic biopsies. Differential diagnosis includes traumatic ulcers, squamous cell carcinoma, and deep fungi. Central caseation necrosis is a classic microscopic feature of tubercular granulomas. Giant cells in the center are characteristic Langhans giant cells found in granulomas. Epithelioid cells form the cellular rim surrounding the central caseation necrosis.
