RESUMO
Hidradenocarcinoma is an uncommon malignant intradermal tumor of sweat gland origin with a predilection for the face and extremities. It is encountered equally in males and females, usually in the second half of life. These tumors tend to be locally aggressive. In our case, the tumor was located relatively superficially but without any apparent connection to the overlying skin. The typical disease course includes local and sometimes multiple recurrences, and some patients develop regional lymph node and distant metastases. These type of tumors in the parenchyma of the breast are extremely rare. We report a case of hidradenocarcinoma in a 77-year-old woman who presented with a palpable inflammatory nodule in the right breast.

Pseudoangiomatous stromal hyperplasia (PASH) is often a microscopic incidental finding in breast biopsies performed for benign or malignant diseases. In rare cases, it presents as a localised breast mass. Since Vuitch et al first described this condition in 1986, only 109 cases of PASH presenting as a palpable or mammographically detectable mass have been documented. PASH is characterised by a dense, collagenous proliferation of mammary stroma, forming inter-anastomosing capillary-like spaces. It is important to distinguish this benign lesion from a low-grade angiosarcoma. Here we describe the clinical, radiological and histological features of a very unusual case of PASH that presented as a rapidly growing breast lesion in a 37-year old woman.

This paper refers to 50 unusual cases of 542 consecutive adult patients who underwent surgery because of acute intestinal obstruction. Of the 38 small bowel cases, 5 were caused by hernias in anomalous recesses (1 prevesical, 2 left paraduodenal, and 2 paracecal hernias), 6 by a gallstone ileus, 14 to the presence of a bezoar or foreign body, 8 to extended postradiation perivisceritis, 3 to Meckel diverticulum volvulus, 1 to transepiploic hernia, and 1 to ileus-Meckel hematoma during anticoagulation treatment. The 12 large bowel cases included 3 diaphragmatic hernias (1 late post-trauma), 3 cases of colo-colic intussusception, 1 case of obstructive cholecystitis, and 5 cases of Ogilvie's syndrome. Major technical problems have to be immediately solved in the case of left paraduodenal, prevesical, or diaphragmatic hernias; however, during laparotomy, there may also be some difficult and unpredictable problems caused by widespread postradiation perivisceritis.
