Diagnostic delay in a patient with reactional lepromatous leprosy treated as testicular tuberculosis.

Leprosy is a chronic neglected and stigmatizing disease. Due to involvement of the peripheral nerves, it can result in physical disabilities, deformities, and emotional damage if not diagnosed and treated promptly. This is the case of a young patient with testicular pain and swelling and no improvement after a specific therapeutic scheme for tuberculosis. Clinical and laboratory reevaluation revealed hypoesthetic skin patches associated with post-burn crusted ulcers on the left arm, thickening of ulnar nerves, atrophy of interosseous muscles of the hands, positive skin smear microscopy, and testicular histopathology with numerous bacilli forming globi. These findings indicated lepromatous leprosy with type II reaction.

Diagnostic delay in a patient with reactional lepromatous leprosy treated as testicular tuberculosis

Abstract Leprosy is a chronic neglected and stigmatizing disease. Due to involvement of the peripheral nerves, it can result in physical disabilities, deformities, and emotional damage if not diagnosed and treated promptly. This is the case of a young patient with testicular pain and swelling and no improvement after a specific therapeutic scheme for tuberculosis. Clinical and laboratory reevaluation revealed hypoesthetic skin patches associated with post-burn crusted ulcers on the left arm, thickening of ulnar nerves, atrophy of interosseous muscles of the hands, positive skin smear microscopy, and testicular histopathology with numerous bacilli forming globi. These findings indicated lepromatous leprosy with type II reaction.

Erythema Nodosum Leprosum Triggered by Antecedent Influenza Vaccine and Respiratory Tract Infection: A Case Report.

We present a patient with new-onset erythema nodosum leprosum months after successful treatment of her mid-borderline leprosy, which was likely triggered by a combination of antecedent influenza vaccination and upper respiratory tract infection.

Primary cutaneous extranodal natural killer/T-cell lymphoma presenting as bilateral erythematous patches on the arms.

Natural killer/T-cell lymphoma is a rare, Epstein-Barr virus-associated type of cytotoxic lymphoma thatpresents mainly in the nasal cavity and its vicinity. Very few cases of primary cutaneous extranodal natural killer/T-cell lymphoma have been reported till date. All the previously reported cases of primary cutaneous extranodalnatural killer/T-cell lymphoma presented as lesions resembling cellulitis, subcutaneous nodules or ulcers. We report a rare case which presented as erythematous and purpuric round patches on the arms and was finally diagnosed as primary cutaneous extranodalnatural killer/T-cell lymphoma, following a skin biopsy. The atypical patchy lesions presented a diagnostic challenge. We herein describe this clinically novel atypical patch-like presentation of primary cutaneous extranodalnatural killer/T-cell lymphoma together with the key histopathologic features and highlights of the previously reported cases.

[Linear tuberculoid leprosy along the lines of Blaschko: a very rare presentation]. / Lèpre tuberculoïde de disposition linéaire blaschkoïde: une présentation exceptionnelle.

BACKGROUND: Leprosy continues to be present in certain regions throughout the world, and the dermatologist plays a central role in its diagnosis. Herein we report a case of tuberculoid leprosy that is atypical in terms of its linear presentation which appears to follow the lines of Blaschko. PATIENTS AND METHODS: A patient from Mayotte was referred to the neurological department for suspected tuberculoid leprosy. He was presenting a deficiency of the ulnar nerve together with neuronal hypertrophy and cutaneous involvement. Dermatological examination revealed linear hypo-aesthetic hypopigmented lesions on the arm and forearm. The atypical clinical presentation also suggested to us pigmented mosaicism or post-inflammatory pigmentation. The biopsy showed granulomatous epithelial dermatitis with perinervous involvement. Imaging examinations confirmed the presence of neuronal hypertrophy. A diagnosis of linear tuberculoid leprosy was made. DISCUSSION: This case illustrates the need to bear in mind a diagnosis of leprosy in the event of hypopigmented lesions, even where they are linear and of Blaschkoid appearance. Several potential hypotheses may account for this particular topographical pattern.
