Gallbladder inflammation is most often determined by the presence of gallstones. Acalculous cholecystitisusually occurs in patients with multiple comorbidities or with an immunosuppressed status, and therefore itsevolution is faster and more severe compared to acute calculous cholecystitis. The presence of a fish bone intothe peritoneal cavity, through a gastrointestinal fistula is not very rare, but acute cholecystitis caused by a fishbone is unexpected. Here, we present the case of a 75-year old woman who had eaten fish two months beforeand presented at the Emergency Room with perforated acalculous cholecystitis and a right subphrenic abscess.The laparoscopic approach permitted the evacuation of the subphrenic abscess, bipolar cholecystectomy andremoval of a fish bone from nearby the cystic duct. Postoperative evolution was uneventful, with hospitaldischarge after five days. The patient was in good clinical condition at two months follow-up.

Objective. We present a rare pathology with uncommon onset. Background. Mucinous cystic pancreatic neoplasms (MCNs) are rare tumors, which generally occur in the fifth and sixth decades of women. Although some tumours are frankly malignant, all are in fact considered to be potentially malignant. Case report. We present the case of a 30-year-old patient, with a 16/11 cm tumor located in the pancreas body, which was diagnosed 8 months after birth. The preoperative assessment of the pancreatic lesion suggested the diagnosis of mucosal cyst neoplasm, without being able to determine its benign or malignant nature. Central pancreatectomy was performed with a good postoperative evolution. Histopathologic result was represented by mucinous pancreatic chistadenoma. Two years after surgical intervention, the patient presented no signs of recurrence or pancreatic (exocrine or endocrine) secretion deficiency. Conclusions. Preoperative imaging evaluation could be suggestive for mucinous cystic tumour, but this cannot specify however the nature of the tumor. The postpartum occurrence could establish a possible relationship between hormonal levels encountered during pregnancy and the development of this tumor, taking into considerations the ovarian-type stroma and the presence of hormone (estrogen and progesterone) receptors in this neoplasm. Central pancreatectomy without anastomosis preserves the functions of pancreas, and also decreases morbidity.

We present a clinical case of synchronous colonic lesions, histologically different, associated with streptococcus gallolyticus subsp. gallolyticus (Sgg)/ Streptococcus bovis biotype I, bacteremia and infective endocarditis. A 53-year-old female, without history of CRC in her family, known with total hysterectomy for uterine fibromatosis, presents to Emergency Department for marked asthenia, nausea, weight loss (10 kgs in the last month), febrile episode associated with severe anemia, symptomatology that has increased in the last two weeks. The patient was admitted in the Internal Medicine Department for further investigations, under the suspicion of sepsis of unknown cause. On blood cultures grew Sgg bacteria. Both transthoracic echocardiography and transesophageal echocardiography were performed and diagnosed infective endocarditis with vegetations of the mitral and aortic valves. Antibiotics treatment was initiated, with ceftriaxone and gentamycin, according to antibiogram results. Severe hypochromic, microcytic anemia, and lack of an infective origin site required digestive endoscopic evaluation, and showed gastritis, ulcerovegetative tumor of the ascending colon and polyp in the rectosigmoid. Resection of rectosigmoid polyp was performed through colonoscopy, and, also, right hemicolectomy with ileo-transverse anastomosis for the ascending colon cancer. Post-operative evolution was favorable. Histological result showed mucinous adenocarcinoma of the ascending colon and tubulovillous adenoma, with moderate dysplasia, in the rectosigmoid. At 6-month, endoscopic evaluation showed normal aspect of anastomosis without presence of other colonic lesions.

Background. Subcutaneous lipomas are one of the most common benign soft tissue tumors seen in clinical practice. They may occur at any age, affecting men more often than women. In therapeutically neglected cases, these lesions may have unusual clinical features. Our case highlights one such form that may be found amongst subcutaneous lipomas. Case report. A 37-year-old man came to the Surgical Clinic for treatment of an ulcerated, pedunculated tumor, measuring 14.5/8/7 cm, located in the sacral region. Clinically, liposarcoma was considered as the diagnosis. Although preoperative fine needle aspiration cytology (FNAC) of the tumor showed mature adipose tissue fragments on all cytological smears, surgical excision was performed, with intraoperative extemporaneous histological examination of the tumor. Histopathological results showed a lipoma with unusual associated features: ulceration of the overlying skin and fatty tissue necrosis, with formation of abscess areas. Conclusion. Therapeutically neglected subcutaneous lipomas may have unusual clinical features, leading to difficulties for both diagnosis and therapeutic approach. This case complements the existing data, from the point of view of the clinical presentation, as well as the histopathological characteristics that a subcutaneous lipoma may have.
