Leprosy associated with psoriasis.

Atypical lesions in relapsed leprosy.

Relapsed cases of leprosy are not common in patients treated regularly with the recommended polychemotherapeutical schemes. Relapses must be readily identified and distinguished from reactions. This article reports a clinical case of relapse in leprosy, with atypical and exuberant skin changes in patient treated for eleven years with a paucibacillary scheme.

Case for diagnosis. Granular cell tumor.

Granular cell tumor is a rare benign neoplasm of neural origin. We report the case of a female patient, 27 years old presenting a brown-red nodule in the right arm, which pathological examination showed to be formed by polygonal cells with eosinophilic granular cytoplasm and immunohistochemistry positive for S100 protein and CD68. Granular cell tumor is usually solitary and in half the cases located in the head and neck areas, 30% of these in the tongue.
