RESUMEN
The actual pathology of the Nicolau syndrome (NS) is still unknown. It is thought to involve direct vascular damage and vasospasm. Many NS cases were reported in the literature but a treatment protocol is still not established. However, after demarcation of the necrotic tissue, surgical intervention is mandatory. Five NS cases with extensive tissue necrosis on the upper lateral gluteal region were analyzed retrospectively. Operative technique was described in details for freestyle perforator-based fasciocutaneous flaps from the gluteal region to reconstruct defects of NS-related tissue necrosis. Freestyle perforator-based fasciocutaneous flaps were used for defect closure in all patients. All flaps survived totally. No complications occurred during the follow-up period. Although rare, NS is a serious complication of inadvertent intramuscular injections. Prevention is the best treatment. However, in case of large-tissue necrosis, freestyle perforator-based fasciocutaneous flaps harvested from the gluteal region is a satisfactory option for reconstruction.
RESUMEN
Goblet cell carcinoid of the large intestine is a rare neoplasm, usually located in ascending colon and rectum. A 60-year-old male patient underwent surgery after the diagnosis of acute abdomen. Exploratory laparotomy revealed perforation with a diameter of 1 cm at the site of the previously performed gastroenterostomy and dilatation of the right colic flexure, secondary to a solid obstructive mass located in the mid-portion of transverse colon. Histopathological investigation of the biopsies, taken from the gastroenterostomy site and the tumor, revealed mixed carcinoid-adenocarcinoma with carcinoid component, predominantly composed of goblet cells. Three cycles of FOLFOX-4 protocol was administered. Following respiratory distress secondary to pulmonary metastasis, the patient's condition deteriorated and subsequently died in the fourth postoperative month. Our aim with this paper is to point out that more cases should be reported for more effective diagnosis, histopathological study, clinical investigation, treatment and prognosis of this specific neoplasm.
