ABSTRACT
O tumor de células gigantes da bainha do tendäo é um tumor de tecidos moles relativamente comum, porém raro na literatura dermatológica. Deve-se a uma proliferaçäo benigna de histócitos na articulaçäo e tecido sinovial peritendinoso que se desenvolve ao redor da bainha do tendäo, ligamento articular e sinovia articular. Apresentamos um caso de localizaçäo em 2§ pododáctilo direito que serve para chamar a atençäo a esse diagnóstico e ao seu diagnóstico diferencial. Foi feita uma revisäo da literatura

We present a patient with a Clark level IV melanoma who received BCG immunotherapy by scarification for 12 months after wide excision. Six months after cessation of treatment, the patient developed regional lymphadenopathy that histology showed to be reactive epithelioid granuloma. Regional immunotherapy thus represents a potentially confusing factor in the post-operative assessment and management of the patient with melanoma.

Injury to the lacrimal gland following fracture of the zygomatic complex is a rare occurrence. Recently, we have observed three cases of herniation of the lacrimal gland between the diastased frontal and zygomatic bone ends. We present these cases, postulate a mechanism for this phenomenon, and advocate open reduction and internal fixation in the primary management of severe distraction.
