Frontal cutaneous leiomyosarcoma: A case report and review of the literature.

Sarcomas are a heterogeneous group of mesenchymal tumours that can affect the skin. They are dominated by Kaposi's sarcoma and dermatofibrosarcoma. Cutaneous leiomyosarcoma is a very rare entity. We report the case of a 78-year-old patient who presented with a primary frontal cutaneous leiomyosarcoma treated surgically with a good outcome at the last follow-up. The objective of this work is to identify the epidemiological, clinical, anatomopathological, therapeutic and prognostic particularities of this pathology through a review of the literature.

An extensor tenosynovitis complicated with extensor tendon rupture revealing a hand tuberculosis.

Tuberculous hand tenosynovitis is a rare localization of tuberculosis. It is dominated by flexor tendon involvement; tenosynovitis of the extensor tendons is exceptional. The diagnosis is usually delayed and sometimes overlooked because of the paucity and the chronicity of the symptoms and signs with the patients often seen at the stage of tendon rupture. We, hereby, report the case of a tuberculous tenosynovitis of the extensors of the left hand having evolved into a ruptured extensor tendons to the 4th and 5th digits. The surgical treatment in conjunction with the antituberculous drugs resulted in the healing of this condition.

Transformation of Dermatofibrosarcoma Protuberans into a Fibrosarcoma.

Dermatofibrosarcoma protuberans is a rare cutaneous mesenchymal tumor characterized by a low potential of malignancy with a very low rate of metastasis but an important rate of local recurrence. Its transformation into a fibrosarcoma is exceptional, responsible for a higher metastatic potential. This transformation implies a closer surveillance. Through a case report and literature review, we will try to expose epidemiological, clinical, histological, therapeutic, and outcome particularities of this entity.

A rare localization of tuberculosis of the wrist: The scapholunate joint.

The tuberculosis of the hand and the wrist is a rare entity. Affecting the scapholunate joint is exceptional. It is usually diagnosed at an advanced stage of carpal destruction, due to slowly development of the symptoms. We report the case of a 58-year-old female, presenting as wrist pain for 3 months. Clinical study showed a local swelling in the left wrist, the mobility of the wrist was normal but painful at the end of motion. The diagnosis of osteoarticular tuberculosis was suspected after radiological and biological study then confirmed after histological study. Antibacillary chemotherapy during 12 months promoted healing and good outcome.

Osteoarticular tuberculosis dactylitis: Four cases.

Tuberculosis dactylitis is exceptional. We report 4 cases of osteoarticular tuberculous dactylitis in 3 women and 1 man. The diagnosis was suspected on chronic and insidious clinical presentation, and confirmed by histology. Patients were treated by anti-tubercular drugs with good functional and radiological outcome in all cases. Clinical and therapeutic issues are discussed by the authors in the context of an endemic country.
