[Lichenoid sarcoidosis on skin tattoos produced by traditional herbal treatments]. / Sarcoidosis liquenoide sobre tatuaje de la piel producida por los tratamientos herbarios tradicionales.

An unusual case of generalised sarcoidosis of the skin on tattoo marks done two years for "medicinal" purposes on a 56 year old woman is presented. The lesions were lichenoid and scaly in appearance with closely grouped papules. The old tattoo marks on the skin were not involved and areas of skin between the new tattoo marks were also spared. In addition, the sarcoidosis lesion were pruritic and burning. The circumstantial evidence indicated the medical agent applied on the tattoo wounds as the provocative factor for the development of sarcoidosis of the skin.

Ectopic lesion of schistosomiasis of the penis simulating an early carcinoma.

A case of ectopic lesion of Schistosoma haematobium of the penis with extensive tissue destruction, simulating an early carcinoma of the penis and almost resulting in an autoamputation of the crown of the penis, is presented. The penis was surgically repaired and the patient treated with ambilhar. In schistosoma endemic area, it is important to think of ectopic schistosoma lesion by such a presentation. Existing theories to explain the presence of schistosoma eggs in locations outside the portal-caval system were reviewed and another one was advanced: its being sexually transmitted.

Keratosis circumscripta. A distinct dermatological entity or a variant of psoriasis?

45 cases of a dermatosis believed to be the same as those originally described by Schrank in 1963 among Nigerian children of Yoruba ethnic origin and named keratosis circumscripta by him are reviewed. All evidences point towards the fact that the dermatosis observed by us as well as those originally described by Schrank are a variant of psoriasis possibly modified by environmental factors. It has therefore been suggested that this dermatosis should not be regarded as a new dermatological entity, and that the original names should be modified. To reflect the original work done by Schrank as as well as the true clinical picture of this dermatosis, the nomenclature psoriasis circumscripta with palmo plantar keratosis is suggested.
