RESUMO
Adenoid cystic carcinoma (ACC) is a rare form of adenocarcinoma that usually begins in the oral cavity, with most cases arising from the salivary glands. Owing to its low incidence, the precise clinical and pathological features, including therapeutic strategy and survival data have not been conclusively reported. ACCs are typically characterized by slow growth, perineural invasion with local and often late recurrence after initial diagnosis. However, some cases demonstrate unusual aggressive biologic behaviour. Herein we describe our experience of two patients with a diagnosis of ACC. These cases highlight the spectrum of the disease with individualized treatment strategies.
RESUMO
Elastosis perforans serpiginosa (EPS) is a rare skin disorder in which there is transepithelial elimination of elastin fibers. It belongs to a group of perforating disorders of which there are four classic types. The EPS type is extremely rare. There have been no previous reports of elastosis perforans serpiginosa occurring as a paraneoplastic phenomenon. We report a case of paraneoplastic elastosis perforans serpiginosa in the setting of stage 4 ovarian cancer.
