Endometrial adenofibroma: a rare entity.

Endometrial adenofibroma is an uncommon mullerian mixed tumor composed of benign epithelial and mesenchymal components. This tumor must be distinguished from other malignant lesions of the uterus, particularly adenosarcoma. The authors report three cases of endometrial adenofibroma and discuss their clinical and histopathologic features. The tumors were diagnosed in patients 31, 55 and 63 years of age. In all three cases polypoid lesions of 13, 2 and 5 cm, respectively, were found in the uterine cavity. A polypectomy was performed in two cases; one patient underwent hysterectomy. Follow-up was available for two patients who are today alive and well.

[Spermatocytic seminoma with rhabdomyosarcomatous contingent].

INTRODUCTION: Spermatocytic seminoma is a relatively rare testicular tumour, not associated with another germ-cell tumour component and characterized by a favourable prognosis. However, discovery of a sarcomatous contingent modifies the prognosis. MATERIAL AND METHOD: The authors report the case of a 50-year-old man with a history of right testicular swelling for 4 years, gradually increasing in size without vaginal effusion. Tumour markers were normal. Ultrasound demonstrated a very large semi-solid semi-cystic testicular mass with a long axis of 14 cm. Orchidectomy was performed. RESULT: Histological examination and immunohistochemistry of the orchidectomy specimen concluded on spermatocytic seminoma associated with a rhabdomyosarcomatous component. CONCLUSION: Only 12 cases of spermatocytic seminoma with sarcomatous component have been reported in the literature The presence of a sarcomatous component confers a very poor prognosis to spermatocytic seminoma.

[Primary hepatic carcinoid tumor: A case report].

Primary hepatic carcinoid tumors are extremely rare, and fewer than 60 cases have been reported in the literature. Long-term follow-up is necessary for establishing the primary nature of liver carcinoids. We report a case arising in a young 20 years-man having Zollinger-Ellison syndrome on presentation. Intensive and careful investigation revealed no other origin of the tumor. Resection is the treatment of choice for primary hopatic carcinoid tumors. Their prognosis seems to be more favorable when compared with other hepatic carcinomas.

[Mature cystic teratoma of the fallopian tube. A case report].

Primary teratomas of the fallopian tube are extremely uncommon. To date, only about 50 cases have been reported in the literature. They occur usually in the fourth decade. There association with nulliparity and reduced parity has been noted. Many have been discovered incidentally and none has been diagnosed preoperatively. The majority are cystic, show great variation in size and are commonly located in the ampulla or the isthmus. They can be intraluminal, attached to the serous surface by a pedicule and rarely intramural. Histologically they are similar to teratoma of the ovary and elsewhere. We describe a mature cystic teratoma of the fallopian tube found incidentally in a 35-year-old woman operated for suspicion of ectopic tubal pregnancy. The feature of benign teratoma of the fallopian tube is discussed.

[Warty dyskeratoma or "follicular dykeratoma": a clinicopathologic features of a new entity].

INTRODUCTION: Warty dyskeratoma is a rare, benign, epithelial tumor characterized by a variable clinicopathologic spectrum. In all cases, lesions revealed foci of acantholytic dyskeratosis. CASE REPORT: A 74-year-old man has for two year developped a single small nodule with a hyperkeratotic area on the scalp. Histopathology revelead a warty dyskeratoma. DISCUSSION: Warty dyskeratoma is an epithelial tumor. Histopathology is important for the diagnosis. On the basis of our findings and from the literature, we propose to discuss the nosologic problem of this entity.

Lymphadenopathic form of alveolar rhabdomyosarcoma: A case report.

We report the case of a special form of rhabdomyosarcoma called "lymphadenopathic" which was reported only two times in the literature. This lymphadenopathic alveolar RMS shows lymph nodes as clinical manifestation mimicking lymphoma with an unknown primary neoplasm. In the case we report, clinical examination, and radiological studies revealed superficial and deep located lymph nodes in association with bilateral pleural effusion. Conventional histological examination showed lymph node infiltration by a metastatic tumour having alveolar pattern. Some of tumour cells were round with multilobed off-centred nucleus and eosinophilic cytoplasm containing fibril material with longitudinal and transverse striation indicating a muscle nature of the tumour proliferation. The immunohistochemical study showed intense and diffuse immunoreactivity of tumour cells for vimentin and a discreet immunostaining by desmin. These findings were compatible with the diagnosis of lymph node metastasis by alveolar rhabdomyosarcoma.

[Endometrial stromal nodule: a case report].

The endometrial stromal nodule is the rarest of the endometrial stromal tumours. It is a benign tumour composed of well-differentiated endometrial stromal cells arranged as a well-circumscribed nodule with smooth, non invasive margins. We describe a case of uterine stromal nodule occurring in a 45-year-old woman with history of menometrorrhagia in which case ultrasonography conclude to a leiomyoma. Epidemiology, pathologic aspects, differential diagnosis, treatment and prognosis are reviewed.

[Multiple lymphomatous polyposis of the gastrointestinal tract: a Tunisian case].

Multiple lymphomatous polyposis is a distinctive primary gastrointestinal lymphoma which endoscopical, histopathological et immunophenotypical characteristics are well known. This lymphoma is rare and its prognosis is bad because of frequency of stage IV patients. We report the case of a 75-year-old male patient with multiple lymphomatous polyposis affecting the rectum, the colon and the stomach associated with an involvement of lymphadenopathies, bone marrow and liver. Treatment by chemotherapy was ineffective and patient dead after 3 sessions of CEOP protocol.

[Abdomino-pelvic actinomycosis. Report of 2 cases].

Actinomycosis is a chronic, granulomatous, suppurative and fistulasing infection related to a gram-positive bacteria (actinomyces israeli). Cervico-facial actinomycosis is the most common localization. The prevalence of abdomino-pelvic actinomycosis is increasing mainly with the increase of the use of intrauterin device. Its clinical presentation is variable and may mimic cancer or tuberculosis. The diagnosis of abdomino-pelvic actinomycosis is hard and most of the cases are detected during surgical exploration. We report two cases of abdomino-pelvic actinomycosis; in the first case, the disease was extended to the caecum and the abdominal wall. The skin biopsies made the diagnosis of actinomycosis, avoiding surgery. In the second case, the diagnosis of actinomycosis is made post operatively because of high suspicion of pelvic cancer. Through these two observations, we review pathogenesis of the disease, its clinical aspects and its diagnostic and therapeutic means.

[Sclerosing stromal tumor of the ovary. Report of 3 cases].

Sclerosing Stromal Tumor (SST) is an uncommon benign tumor of the ovary, distinct from thecoma and fibroma because of predominant occurrence below 30 years of age, lack of hormonal manifestations and histologic heterogenity. Three cases of SST occuring in a 15, 26 and 56-year-old females are reported. Review of the literature and clinicopathological features are described in the present article. Histogenesis and differential diagnosis are also discussed.

[Endometrial actinomycosis. Two case reports].

Actinomyces is an aerobic, Gram positive bacteria saprophyte of the genital tract. The endometrial involvement is extremely rare. The authors report two cases of pelvic actinomycosis in a 58 and 55 year old women, the second using intrauterine device for 11 years.
