Sporotrichoid nocardiosis with cutaneous dissemination.

Dissemination of primary cutaneous nocardiosis is a rare event. A 37-year-old man working as farmer presented with multiple painful suppurative nodular and ulcerative skin lesions over left lower extremities, in a linear pattern, with duration of five months and single painful nodule over right elbow since last three months. We found the presence of beaded filamentous bacteria in Gram stain smear and partial acid fast stain, from the smear taken from pus. Patient responded well to cotrimoxazole therapy. Hence, we confirm our diagnosis of sporotrichoid pattern of cutaneous nocardiosis with dissemination to other cutaneous area.

Cutaneous findings in five cases of malaria.

Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC). Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

Kaposi's sarcoma: a presenting sign of HIV.

Kaposi's sarcoma (KS) is a multifocal cutaneous and extra cutaneous vascular proliferative disorder. In India, there are only a few cases of HIV-associated KS in published literature. A 26-year-old married man presented with asymptomatic elevated skin lesions over the face, trunk, both upper limbs and lower limbs with a duration of one-and-a-half months. Cutaneous examination revealed multiple violaceous papules and nodules, on the face (right upper and lower eyelids, upper lip), trunk and proximal part of both limbs. Oral cavity showed erythematous plaques, two in number, on the hard palate. Skin biopsy showed proliferation of thin walled capillaries with formation of slit like spaces, spindle cell proliferation, abundant extravasation of RBCs and moderately dense inflammatory infiltrate in the dermis. Thus a clinical diagnosis of cutaneous KS was confirmed. On testing with ELISA for HIV, the patient was for the first time diagnosed as HIV reactive. Thus KS was the presenting manifestation of HIV disease.
