Lipomas are rarely localized at the hand, and more unfrequently at the anatomical snuffbox. We report a case of a lipoma that compressed the lateral branch of the superficial sensory branch of the radial nerve., (Copyright © 2010. Published by Elsevier SAS.)

Pilomatrixoma is a benign skin neoplasm of the hair follicle. It's common in the pediatric population. It's usually misdiagnosed and confused with other skin lesions. Head and neck represent the usual locations. The extremity remains an exceptional location. Through an observation of a pilomatrixoma of the leg in an adult patient treated surgically without recurrence, different diagnostic and therapeutic aspects of this pathology will be recalled.

Ischemic fasciitis, also called atypical decubital fibroplasia, was recently described as a distinctive fibroblastic proliferation occurring predominantly in elderly, bed-ridden individuals. It is very rare. Forty cases only are reported in the literature. We report the observation of a 50-year-old patient, having an antecedent of prolonged confinement, who presents since 1 year a tumefaction compared to the higher end of the tibia of soft consistency with inflammatory signs in glance. The pathologic examination shows a pseudo tumoral lesion of ischemic fasciite type. Through this observation, we suggest to review the various problems of diagnostic differentials in particular with a sarcoma of soft tissues and to discuss the anatomoclinic features of this recent description lesion.

Plexiform schwannoma is an exceptional schwannoma subtype. It's a benign nerve sheath tumor. Mainly, it's solitary, asymptomatic and slowly growing nodule that occurs in the subcutis or dermis. Histology gives the diagnosis. The authors report a case of solitary superficial plexiform schwannoma of the right forearm of a patient aged 22. A review of literature is done.

Subcutaneous localization of hydatid cyst is uncommon even in endemic zone. Symptoms are often discrete. Diagnosis is confirmed by imaging: ultrasonography and/or magnetic resonance imaging, thus avoiding any untimely gesture. The treatment is surgery. Authors report a case of unusual subcutaneous localization of solitary hydatid cystis in the gluteal area.
