RESUMO
Bacillary angiomatosis (BA) is a recently recognized bacterial infectious disease that is mainly seen in patients with the acquired immunodeficiency syndrome. BA has rarely been reported in immunocompetent individuals. A case of BA of the scalp in an immunocompetent patient, who was human immunodeficiency virus seronegative, is reported. The importance of differential diagnosis of this lesion is emphasized.

Collecting duct carcinoma of the kidney is a rare variant of renal cell carcinoma. Hematuria is the most common presenting symptom. This tubulopapillary tumor arises from or differentiates forward to medullary collecting tubules. It is typically centered on the medulla of the kidney and extends into the cortex with a desmoplastic reaction. There are few reports documenting the clinical presentation and long-term prognosis. We describe a case of this uncommon tumor with clinical, histological and immunohistochemical features and review the literature.

Renomedullary interstitial cell tumor was first introduced by Lerman and co-workers. These lesions have been referred to as medullary fibromas. The ultrastructural studies showed that the spindle cells throughout the stroma have the features of medullary interstitial cells. These benign tumors with specific histology are rare since they are incidental findings at autopsies. We report here a case of renomedullary interstitial cell tumor in a 55-year-old woman.
