[Primary cutaneous extraskeletal Ewing's sarcoma].

BACKGROUND: Cutaneous extraskeletal Ewing's sarcoma is rare, being seen principally in children. We report a case of cutaneous sarcoma in the sole of the foot in a child. CASE REPORT: A 9-year-old child with no medical history of note was presenting a skin tumor for 3 months on the heel of the right foot. This tumor was burgeoning and painful and measured 3.5 cm in diameter; it was ulcerative at the surface and covered with a crust. Histological and immunohistochemical examinations confirmed the diagnosis of Ewing's sarcoma. Staging examinations proved negative and the patient underwent polychemotherapy, resulting in complete regression of the tumor. COMMENTS: Until 1998, 37 cases of cutaneous and subcutaneous Ewing's sarcoma were reported, being seen in 21 girls and 16 boys. Mean age at diagnosis was 15 years and mean tumor size was 3 cm (range: 1 to 12 cm). The tumors were observed throughout the body, being seen in the sole of the foot in 2 cases. Confirmation of the diagnosis was made by histological examination (malignant proliferation of small round cells in the dermis), immunohistochemical examination (CD99+) and cytogenetic analysis (translocation between chromosomes 22 and 11). The prognosis for cutaneous Ewing's sarcoma appears more favorable than that of Ewing's sarcoma in bone. Of the 37 patients treated, 7 had metastases and 2 presented relapse. Treatment for cutaneous Ewing's sarcoma, though not codified, consists of polychemotherapy associated with surgery and/or radiotherapy.

[Tubo-ovarian actinomycosis ruptured in the sigmoid colon].

Actinomyces is an anaerobic, gram-positive bacteria saprophyte of the oral cavity, lungs, genital and gastro-intestinal tracts. Tubo-ovarian infection is rare. The authors report a case of tubo-ovarian abscess, due to actinomyces ruptured in the sigmoid and diagnosed in a 30-year-old woman using an intra-uterine device for more than 5 years. After salpingo-oophorectomy and partial sigmoid resection, pathology confirmed the diagnosis.

[Digital tuberculous revealed by trauma].

Tuberculous dactylitis is an uncommon condition which is particularly difficult to differentiate from other lesions, particularly tumors. Diagnosis must be confirmed by histology and/or bacteriology studies. We report the case of a 64-year-old diabetic woman who consulted for a painful tumefaction on her fourth finger of the left hand which had developed after minimal trauma. The x-ray of the hand visualized multiple bony defects involving the second phalanx of the fourth finger and a fracture. Pathology examination of a biopsy specimen revealed granulomatous osteitis with typical caseous necrosis. The clinical signs and radiographic images resolved after anti-tuberculosis treatment.

[Sarcoid-like necrotizing granulomatosis. A case report].

Necrotizing sarcoid granulomatosis is a rare granulomatous pulmonary angeitis that was first described by Liebow in 1973. We report the case of a 36-year-old woman who was admitted for exploration of chest pain, cough and fever at 39 degrees which had progressed for more than 2 months. Chest X-ray showed several inconstant pulmonary opacities. The physical examination, the radiographic and endoscopic aspects were non-specific. The diagnosis was made only by open lung biopsy which showed histological findings of necrotizing sarcoid granulomatosis. The opacities disappeared with no recurrence spontaneously at one year.

[Mesenchymatous chondrosarcoma of the superior maxillary bone. A case report].

The authors report a new case of mesenchymal chondrosarcoma (MCS), occurring in the upper jaw bone of a 19 year-old woman. Radiographic picture in the bone shows an aggressive osteolytic tumor suspect of malignancy. An incisional biopsy was practiced and the histologic examination has confirmed the diagnosis of MCS. Treatment have consisted of a large resection of maxilla with additional irradiation therapy. The postoperative course was marked by recurrence of the lesion one year later.

[Buschke-Loewenstein giant condyloma in the perianal region with inguinal invasion: a case report].

The giant condyloma acuminatum of the perianal region is a tumor characterised by its large size with the propensity to infiltrate into deeper tissues, contrasting with a microscopically benign pattern. The evolution after malignant transformation of condyloma and lymph node invasion is rare. However it is exceptionally observed a lymph node invasion of microscopically benign condyloma acuminatum. The authors report a case of microscopically benign giant condyloma acuminatum of the perianal region associated with inguinal invasion, discovered in a 47 year-old man. Treatment consists in extensive surgery of the tumor and inguinal nodes, followed by a radiation therapy.

[Polymorphous low-grade adenocarcinoma of the accessory salivary glands--a case report].

A case of polymorphous low-grade adenocarcinoma of minor salivary gland is reported. This tumor was first described in two clinical case series in 1983. Before that time most of these neoplasms were diagnosed as benign salivary gland neoplasms (pleomorphic adenomas) or salivary malignant conditions (malignant pleomorphic adenomas, adenoid cystic carcinomas, papillary adenocarcinomas and adenocarcinoma not otherwise stated). This neoplasm, with few exceptions, originates in minor salivary gland tissues of the palates or buccal mucosa. It is characteristically slow to enlarge. Clinical reports show the neoplasm present for many years before diagnosis. The tumor have a variety of morphological patterns, a cytological uniformity and an infiltration into adjacent structures. The treatment is a wide local excision. Recurrences and lymph node metastases are rare.

[Placental metastasis of breast cancer].

The authors report an unusual case of extensive placental micrometastases of breast carcinoma occurring in a 43 years-old woman, seen at 31 weeks gestation with metastatic disease. A female infant was delivered by caesarean section. Physical examination of the newborn was normal. The mother rapidly died of metastatic disease. Placental metastases from maternal tumours are rarely reported in the literature. The diagnosis is made by histologic examination. Placental metastases are associated with bad prognosis for the mother. The foetus is usually free of tumours when the metastases are limited to the intervillous space.
