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.
Background/Aims: Liver adenomatosis is an uncommon condition and so far only 13 cases fulfilling the requirements for its diagnosis have been reported in the literature. Optimal treatment of the disease and follow-up criteria are still the subject of debate. Methods: We report on 2 cases of liver adenomatosis. In both cases definite diagnosis was obtained only intraoperatively on biopsy. Results: In neither case was liver transplantation done, due either to patient refusal or foreseeable poor compliance. Prolonged strict follow-up failed to demonstrate malignant changes. Conclusions: Removal of the huge masses often responsible for abdominal pain is the only real indication for resective surgery. Orthotopic liver transplantation should be reserved for those cases in which malignant changes are suspected due to elevation of the α-fetoprotein concentration or gross modifications in the shape of the hepatic lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
