[Myxoid pleomorphic fibroma of the skin]. / Fibroma cutáneo pleomórfico mixoide.

Pleomorphic fibroma of the skin was described by Kamino et al 1 in 1989. It is a benign fibroblastic proliferation with cytologic atypia. This article describes a case of a myxoid variant of pleomorphic fibroma of the skin.

[Non-functional renal paraganglioma associated with carotid paraganglioma and appendicular mucocele]. / Paraganglioma renal no funcionante asociado con un paraganglioma carotídeo y un mucocele apendicular.

OBJECTIVE: A case of nonfunctional renal paraganglioma associated with appendicular mucocele and metachronic carotid paraganglioma is presented. METHODS/RESULTS: A 68-year-old patient consulted for abdominal pain. Patient evaluation with US, CT and opague enema showed an elongated mass that compromised the cecum and a solid mass in the right kidney. The patient underwent appendectomy and radical right nephrectomy. The anatomopathological findings showed an appendicular mucocele and renal paraganglioma. The postoperative hormone analyses were normal. A carotid paraganglioma was removed 8 months later. CONCLUSIONS: Renal tumors arising from neural crest cells are uncommon. To our knowledge, this is the third case of nonfunctional renal paraganglioma reported in the literature. The associated appendicular mucocele was an incidental finding.

[Pure prostatic leiomyoma]. / Leiomioma prostático puro.

We report a case of pure leiomyoma of the prostate, an uncommon benign tumor with a leiomyomatous component distinct from benign prostatic hyperplasia. The literature is reviewed and several considerations are put forward relative to the etiopathogenesis, clinical and anatomopathological features, differential diagnosis and prognosis of this tumor.

[Jaundice secondary to intrahepatic deposit of light chains as a presenting form of multiple myeloma]. / Ictericia secundaria a depósito intrahepático de cadenas ligeras como forma de presentación de un mieloma múltiple.

In the disease caused by deposit of light chains, nephropathy is the earlier and most frequent clinical manifestation; and although the liver is the extrarenal organ most frequently affected, its affection is rare without renal deposit of light chains. Bearing this in mind, we present the clinical and evolutive characteristics of a patient diagnosed of IgG Kappa multiple myeloma, whose first manifestation was a jaundice syndrome with intrahepatic deposit of light chains documented in the anatomopathologic study and in which, despite presenting renal failure, deposits of light chains were not observed in the renal biopsy. We review the medical literature on this topic.

[Bladder amyloidosis]. / Amiloidosis vesical.

We present a case of Vesical Amyloidosis (V.A.) in a woman with Rheumatoid Arthritis. Clinical data, other locations and Histochemical findings are consistent with Secondary Amyloidosis. After T.U.R., she was treated with Dimethylsulfoxide (DMSO) and Colchicine. Her severe hematuria disappeared.
