Kaposi sarcoma following postmastectomy lymphedema

Classical Kaposi sarcoma (KS) usually appears on lower extremities accompanied or preceded by local lymphedema. However, the development in areas of chronic lymphedema of the arms following mastectomy, mimicking a Stewart–Treves syndrome, has rarely been described. We report an 81‐year‐old woman who developed multiple, erythematous to purple tumors, located on areas of post mastectomy lymphedema. Histopathological examination evidenced several dermal nodules formed by spindle‐shaped cells that delimitated slit‐like vascular spaces with some red cell extravasation. Immunohistochemically, the human herpesvirus type 8 (HHV‐8) latent nuclear antigen‐1 was detected in the nuclei of most tumoral cells confirming the diagnosis of KS. Lymphedema could promote the development of certain tumors by altering immunocompetence. Although angiosarcoma (AS) is the most frequent neoplasia arising in the setting of chronic lymphedema, other tumors such as benign lymphangiomatous papules (BLAP) or KS can also develop in lymphedematous limbs. It is important to establish the difference between AS and KS because their prognosis and treatment are very different. Identification by immunohistochemistry of HHV‐8 is useful for the distinction between KS and AS or BLAP.     

Encuesta nacional sobre valoración de la actividad de los médicos internos residentes en los servicios de urgencias españoles

Introduction

The care activity of internal resident doctors is common to practically all medical and surgical training programs; however, there are no national data available regarding the situation of this activity from the perspective of the resident. The present study has sought to collect the opinion of the resident internal physicians on the health care performance and the teaching character that links them to their corresponding emergency departments, in the following areas: overall training value, appreciation of the workload, characteristics of the morning rotation, supervision or tutoring, etc.

Baboon‐Like Syndrome in Children

Baboon syndrome is a combination of diffuse symmetrical erythema on the major flexural areas and V‐shaped erythema on both upper anteromedial thighs. Infectious agents have been described as possible triggers. We describe for the first time baboon syndrome in a child induced by a coinfection with Epstein‐Barr virus and cytomegalovirus.

Should Idiopathic Facial Aseptic Granuloma Be Considered Granulomatous Rosacea? Report of Three Pediatric Cases

Abstract: Idiopathic facial aseptic granuloma (IFAG), or pyodermite froide du visage, is a skin disease reported only in children and characterized by painless red nodules usually located on the cheeks. Its etiology is still unclear, but some authors considered the possibility that IFAG might be included in the spectrum of granulomatous rosacea (GR). The histopathological features of IFAG and GR are quite similar, showing perifolliculitis, granulomas, folliculitis, and lymphocytes and plasmacells around epithelioid histiocytes. In the present article, we discuss three cases in which an association between a facial nodule, compatible with both IFAG and GR, and recurrent chalazia make us support the hypothesis that IFAG should be considered as GR.
