Introduction: Pilonidal disease is a chronic inflammatory process resulting from impaction of natal cleft hair into the subcutaneous tissues creating an abscess or a draining sinus over the sacrococcygeal area. Malignant transformation occurs in around 0.1%, mainly into squamous cell carcinoma (SCC) type. Wide excision with tumor-free margins remains the treatment of choice. Multiple closure techniques were settled and the best one ought to be chosen in a context malignancy and future radiological treatment. Case Presentation: We describe the management of a case of a 69-year-old male with chronic pilonidal disease, recurrent after 25 years found on final pathology to undergo malignant transformation into SCC. Wide and aggressive excision were performed with new margins and with periosteal excision of the sacrum and coccyx. rotational myocutaneous gluteal flap was done for closure of the wound in order to ensure better satisfactory esthetic results without a delay in future treatment. Conclusion: The progression of a chronic pilonidal disease into SCC is a rare but serious complication. The diagnosis is confirmed by biopsies. Workup for metastasis should be made before aggressive surgical excision. Oncoplastic surgeries is recommended for satisfactory results. Routine follow-up postoperatively should be considered due to high rate of recurrence by physical examination and imaging.

Anastomotic leaks and gastric fistulas are recognized complications after sleeve gastrectomy and Roux-en-Y gastric bypass. They are, however, almost unheard of following a one-anastomosis gastric bypass. A gastrobronchial fistula, an exceedingly rare complication after bariatric surgery, has to date never been described following a one-anastomosis gastric bypass. Furthermore, there is no consensus regarding the management of this challenging complication. In our case, we present a patient who was discovered to have a gastrobronchial fistula 5 years after a one anastomosis gastric bypass. After 2 failed attempts at endoscopic stent placement, the patient was successfully managed with a laparoscopic Roux-en-Y gastrojejunostomy over the fistula.

Malignant insulinomas, a rare life threatening pathology, exists in literature as an entity that constitutes 10% of all insulinomas and often present as multi-centric macro nodules with multiple lymph nodes or liver metastases before diagnosis. We report a rather rare case of a 68 year old male with a 30 years history of uninvestigated severe hypoglycemic attacks that improved on glucose intake. Blood tests showed a decreased value of glycemia (45 mg/dL) associated with increased insulin level (54 μU/ml) and an increased glycemia/ insulinemia ratio of 0.83 supporting the diagnosis of insulinoma. Abdominal CT showed a 4 cm mass localized in the head of the pancreas with atrophic body and tail, no signs of distant metastatic disease. A concomitant diagnosis of primary hyperparathyroidism raised, based on elevation of calcium associated and high level of PTH. The coexistence of the two endocrinopathies suggested the presence of type 1 multiple endocrine neoplasia (MEN I). Based on the workup suggesting a benign insulinoma with no signs of metastatic disease, co-existing with debilitating symptoms of hypoglycemia, pancreatectomy with lymph node dissection was performed. Histo-pathological examination returned surprisingly positive for malignant neuro-endocrine tumor with positive lymph nodes. In that domain, we summarized the literature discussion of neuroendocrine tumors, elaborating on malignant insulinoma diagnosis and management. Furthermore, what our article is trying to lay upon existing literature is a case of a long standing existent MEN 1 malignant insulinoma manifesting as a remarkably slow progressive disease of 30 years’ timeline versus a less likely chance of a transformation from benign insulinoma to malignant Keywords: neuroendocrine neoplasm; pancreatectomy; MENI; malignant insulinoma; chronic hypoglycemia.

Introduction In patients who underwent pancreatoduodenectomy for management of Chronic pancreatitis, early and late anastomotic failure can occur [ 1 ]. Nevertheless, taking into consideration that most pancreatic head resections are performed for malignant disease with poor prognosis, long term pancreatico-jejunal anastomotic durability has not been well examined; similarly, the management of its stenosis has not been well assessed [ 1 ]. Case Here we present a case of a 69 years old male patient with history of chronic alcoholic pancreatitis and ampullary fibrosis managed by pancreatico-duodenectomy presenting for 10 years delayed onset of recurrent acute pancreatitis with signs of pancreatico-jejunal anastomotic stenosis, managed surgically with revision of pancreatico-jejunal anastomosis. Conclusion Our case report might hold strongly for bringing up a purposeful approach, and be an insight to take into consideration in approaching pancreatic anastomosis, especially when pancreatic resections are utilized for treating benign pathologies.
