[Primary mucinous carcinoma of the skin. A case report].
Primary mucinous carcinoma of the skin is a rare sweat-gland neoplasm with a high recurrence rate. We report a new case of a primary recurrent mucinous carcinoma of the face in a 59-year-old man. Histopathologic examination of the neoplasm showed epithelial islands floating in mucoid material compartmentalized by fibrous septa. Cytokeratin 7, protein S100, estrogen and progesterone receptors were detected at immunohistochemical study, while cytokeratin 20 and actin were undetectable. Histologically, mucinous carcinoma of the skin can be mistaken for a metastasis from extracutaneous sites, particularly the breast or the gastrointestinal tract. Mucinous carcinoma of the skin has a relatively good prognosis with rare distant metastases, but high recurrence rate.

[Inverted papilloma of the bladder: diagnosis and course].
OBJECTIVE: To analyse the diagnosis, treatment and clinical course of inverted papilloma of the bladder MATERIALS AND METHODS: Between January 1980 and January 2004, 12 patients with an inverted papilloma of the bladder were included, representing 0.36% of all bladder tumours treated over the same period. RESULTS: This series consisted of 10 men and 2 women with a mean age of 62 years (range: 42-83 years). The most frequent presenting complaint was macroscopic haematuria (10/12 cases), associated with signs of bladder irritation in 8 cases. This lesion was solitary and frequently located in the trigone (7/12 cases). An associated transitional cell carcinoma was diagnosed in 5 cases. CONCLUSION: Inverted papillomas of the bladder are rare, benign tumours that can be associated with urothelial carcinoma, requiring rigorous surveillance.

[Pelvic ganglioneuroma. Report of a case].
Ganglioneuroma is a rare benign tumor. It is the most mature of neurogenic tumors. We report a case of a pelvic ganglioneuroma diagnosed in 24-year-old pregnant woman who presented with an urinary infection. Echographic examination suggested an ovarian mass. At surgical operation, the tumor was close to the sacrum. A total resection of the tumor was performed. Pathological examination proved it as a ganglioneuroma. Sixteen months later, the patient is free from disease.

Scrotal calcinosis: pathogenesis and case report.
Scrotal calcinosis (SC) is a rare and benign condition defined as the existence of multiple calcified nodules within scrotal skin. We report the case of a 39-year-old male patient with a three-month history of scrotal tumours that increased rapidly in number and size. Histopathological and immunohistochemical investigations showed no evidence of epithelial structure. Whether SC is idiopathic or the result of the calcification of pre-existing cysts is still a controversial issue. In some cases, as well as in our case, no evidence of cystic structure was found around calcified material, despite minutely careful studies. This suggests that SC might be truly idiopathic.

[A particular hepatocellular carcinoma combining the ordinary and the fibrolamellar variant].
Fibrolamellar carcinoma (FLC) of the liver is a rare variant of hepatocellular carcinoma (HCC) occurring on non cirrhotic liver. Since its first description by Hugh Edmondson in 1956, 200 cases of FLC have been reported in the literature, but only some cases describe the association of the ordinary HCC with the FLC within the same lesion. We report in this study the case of a 14-year-old female patient with a hepatic mass whose radiological aspect evoked a nodular and focal hyperplasia. Histologically, this tumor was composed of area of FLC mixed with ordinary HCC. Staining for cytokeratine 7 was positive in the FL component and negative in the ordinary HCC component.

[Prognostic value of clinicopathologic factors in superficial bladder tumors: a retrospective analysis].
OBJECTIVE: To study, through a series of superficial bladder tumors, the prognostic factors of recurrence and tumoral progression. MATERIALS AND METHODS: This is a retrospective study of a series of 59 urothelial tumors of the bladder at stage pTa or pT1. The following parameters were considered: age, sex, treatment, stage and grade. The chi square test was used in search of a correlation between the different parameters and the course (recurrence and progress) of the disease. A multivariate analysis was undertaken by integrating factors correlated with the course. RESULTS: Thirty two tumors (54 %) had recured versus 27 (46%) without recurrence. Eight tumors (25 %) progressed in grade and 4 (12,5 %) had become infiltrative. Age beyond 65 years, tumoral size > 3 cm and multifocality were predictive factors of recurrence with a relative risks of 2,36, 3,28 and 3,88 respectively. In a multivariate analysis, these factors remained significant with adjusted relatif risks respectively of 1,36, 1,6 and 1,7.

[Retroperitoneal Castleman disease].
Castleman disease or angiofollicular lymph node hyperplasia is a rare disease of unknown cause with polymorphic clinical features that raises many diagnostic and therapeutic problems. The unifocal, localized, pseudoneoplastic form, first described in 1956, has a good prognosis, but the multifocal form has a more aggressive course. Three histological types have been identified: hyaline vascular, plasma cell and mixed. The authors present a case of hyaline vascular unifocal Castleman disease. A retroperitoneal mass was discovered incidentally during follow-up ultrasound examination in a 38-year-old woman treated for recurrent renal stones. On CT examination, a solid mass measuring 9 x 8 x 6 cm raised a problem of differential diagnosis with other retroperitoneal masses. CT-guided biopsy was inconclusive and the diagnosis was finally established by tumour excision and histological examination. The immediate and subsequent postoperative course was uneventful.
