[Angiosarcoma of the spleen]

Primitive splenic tumors are extremely rare. We report a case, the first at S. José-Hospitais Civis de Lisboa, of a 70 year old woman who presented splenomegaly. She had pelvic irradiation in her past history. MRI revealed a splenic mass characterized as vascular on angiography. She is doing well 12 months after splenectomy. We have found 61 reported cases of this rare tumor whose etiopathogeny is unknown. Early splenectomy should be the first therapeutical approach, since spontaneous rupture is very common and was the feature presented in 34% of patients in the series by Autry et al. As far as cytostatic chemotherapy is concerned, the rarity of this tumor precludes any conclusion about its efficacy, but in metastasized forms it seems that chemotherapy for soft tissue sarcomas may be effective.

Dermatophilus congolensis human infection

Four cases of human dermatophilosis observed in Rio de Janeiro, Brazil, are reported. Data that suggest nail infection by Dermatophilus congolensis are presented. The clinical spectrum of the disease ranged from an asymptomatic infection to a pustular eruption. Our findings suggest that epidermal Langerhans cells play a role in the pathogenesis of the infection.

[Undifferentiated sarcoma of the liver in the adult]

A case of undifferentiated sarcoma of the liver with heart, lung and liver metastases, is reported. We emphasised the role of ultrasound for the early diagnosis of cardiac metastases. As far as we know there is no other report on this tumour in portuguese literature.
