This systematic review and meta-analysis highlights the prognostic role of Hsp90 and Hsp70 expression in breast cancer. Further high-quality studies, with detailed reporting are needed to provide epidemiological evidence complementing the findings of ongoing clinical trials on Hsp inhibitors.
Dermatofibrosarcoma protuberans (DFSP) is a superficial mesenchymal neoplasm that originates from the dermal fibroblasts and tends to be locally aggressive. Although infrequent, it is one of the most common cutaneous sarcomas. It mainly affects young and middle-aged patients 20 to 50 years old. Any area of skin may be involved, but the most common sites of presentation are the trunk and extremities. DFSP of the breast is extremely rare. It classically presents as a nodular, exophytic, cutaneous mass, though initially it can manifest as a flat plague and can show persistent but slow growth for many years. Due to increased risk of local recurrence, the standard of care for localized disease is surgical excision with adequate margins. Wide local excision is the most common technique used, but as an alternative Mohs micrographic surgery has emerged as a procedure that offers lower local recurrence rates. Metastases are rare but have been previously reported. In such patients, treatment with imatinib or radiotherapy can be considered. The current case presents a 52-year-old lady with DFSP of the breast that was successfully managed by the Breast Unit of Athens Medical Center-Psychiko Clinic.
Doppler-guided hemorrhoid artery ligation seems to be a safe and effective treatment option for all grades of hemorrhoidal disease. Further prospective randomized comparative studies are needed in order to fully evaluate the true role of DG-HAL in the surgical armamentarium.
Introduction. We report the case of an appendiceal carcinoid tumor within an Amyand's hernia, presenting as an incarcerated right inguinal hernia. Presentation of Case. A 52-year-old male presented in the emergency department due to a persistent right inguinal pain. Clinical examination revealed a tender right groin mass. Laboratory tests revealed leukocytosis and an increased serum CRP. Under the diagnosis of an incarcerated right inguinal hernia, an emergency operation was taken. Intraoperatively, an inflamed appendix and a part of the cecum were found in the hernia sac. The operation was completed with an appendectomy and a modified Bassini hernia repair. Histological examination revealed a carcinoid tumor, resulting in the performance of a right hemicolectomy. Discussion. Amyand's hernia is estimated to account for 0.4% to 0.6% of all inguinal hernias. Coexistence of an Amyand's hernia and a neoplasia is quite rare. Carcinoids are the most frequent tumors found in the appendix, with the size of the primary tumor to be considered the most important prognostic factor and the basis upon which the operative plan is decided. Conclusion. A malignancy of the appendix should always be in the differential diagnosis of a right inguinal mass, in order to provide optimum surgical treatment.
Matrix-producing carcinoma (MPC) is a rare subtype of metaplastic breast carcinoma (MBC) that was first described in 1989 by Wargotz and Norris. It accounts for less than 1% of breast carcinomas and has distinctive clinical, morphological, and immunohistochemical features. Histologically it consists of invasive carcinoma of no special type with transition to cartilaginous or osseous matrix without a spindle cell component. Data on this entity are limited with the literature consisting mostly of case reports and a small number of case series. We report a case of matrix-producing breast carcinoma, with excellent clinical outcome. We also discuss the histogenesis, imaging, histological, and immunohistochemical characteristics, treatment, and focus on the differential diagnosis of this rare tumor.
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.
