Pyoderma vegetans is diagnosed on clinical and histological criteria. Differentiation must be made from disorders such as pyoderma gangrenosum, Sweet's syndrome, and deep fungal infections. We illustrate a case of pyoderma vegetans and review the literature on this rare disorder. Clinical and histological criteria for diagnosis are presented, as well as differentiation from some mimicking disorders.

Fixed drug eruption to nonsteroidal anti-inflammatory drugs is common. However, FDE due to naproxen, one of the NSAIDs, is rarely reported. We describe an unusual case of FDE, which recurred at each menses.

Onchocerciasis was diagnosed when a skin biopsy specimen immersed in saline revealed microfiliariae. The patient was a 22-year-old student from Cameroon, West Africa, complaining of small, recurrent, pruritic papules on his thighs. Chemotherapy with ivermectin, an established antiparasitic agent with newly recognized anti-onchocercal potential, was well tolerated, and microfilariae were not detected in post-therapy skin biopsy specimens. The diagnosis of onchocerciasis should be entertained in individuals returning or emigrating from endemic areas.
