[Total androgenic insensitivity syndrome. Presentation as giant inguinal mass].

The androgen insensitivity syndrome is the most frequent form of masculine psedohermafroditism. The affected patients present female phenotype without sexual ambiguity but with karyotype 46 XY. In this syndrome the frequency of malignización of the testicles increases progressively with the age, because of this, the importance of an earlier diagnosis. We present a case of later diagnosis late of the androgen insensitivity syndrome, that debut with a great inguinal mass.

[Retrovesical schwannosarcoma].

Contribution of one case of retrovesical schwannosarcoma in a 23-year-old female patient, with discussion of signs and symptoms, diagnosis and treatment. Retroperitoneal schwannosarcoma is an extremely uncommon tumour. Diagnosis is always histologic and immunohistochemical. This is an extraordinary aggressive tumour, with low response to chemo- and radiotherapy. Surgery is the only curative treatment, and presents a high index of recurrence. Prognosis is sombre. We support the most radical surgical approach possible as the only definite diagnostic possibility, since it provides the best survival indexes and in any case, improves symptomatology of tumours not completely resectable.

[Transitional-cell sarcomatoid carcinoma of the renal pelvis with osteoclast-type giant cells. Review of the literature].

One case of transitional cells carcinoma with sarcomatoid pattern, located in the renal pelvis in a 77 year-old male with haematuria. The tumour also expressed a non-neoplastic component of osteoclast-like giant cells which probably represent a stromal reaction of the host to the neoplasia. The tumoral cells co-express keratin and vimentin, two strands of the cytoskeleton specific for epithelial and mesenchymal cells, respectively. We speculate with the possibility of the tumoral cells fusocellular morphology being related to the vimentin expression. A review of the literature is also included.

[Xanthogranulomathous pyelonephritis (and cystic dysplasia) in a newborn].

The authors present a case of diffuse xanthogranulomatous pyelonephritis in a new-born baby which, according to the literature reviewed, is the youngest case reported throughout the world. They stress the coexistence of two facts not mentioned in the cases reviewed: --Segmentary cystic dysplasia.--Xanthogranulomatous disorder in the suprarenal gland. It is also interesting due to the presence of chronic contralateral pyelonephritis. They comment upon the special features of the etiopathogeny, anatomopathology, clinical picture, diagnosis and treatment of this rare disorder.
