Post-traumatic chest wall lipoma in a violinist: fact or fiction?

Lipomas are known to be the most common benign subcutaneous soft tissue tumours, with a prevalence of 2.1% [1]

Trichophagia as a cause of acute appendicitis in a patient with bipolar disorder

Acute appendicitis is one of the most common abdominal surgical emergencies worldwide. Clinical diagnosis is possible in most of the cases although imaging modalities may become necessary if the diagnosis is uncertain. Appendectomy, preferably the laparoscopic approach, still remains the gold standard treatment to date. The pathophysiology usually includes luminal obstruction by an appendicolith or lymphoid hyperplasia and rarely parasitic infections. In this report, we present an extremely rare case of a patient with diagnosis of bipolar disorder and a history of trichophagia resulting in trichobezoar formation within the appendiceal lumen leading to acute appendicitis

Primary diffuse large B-cell lymphoma of the sigmoid colon

Introduction: Extranodal lymphomas are commonly encountered in the gastrointestinal tract but lymphomas of colon and rectum are rare. Non-Hodgkin lymphoma is the most common type of colonic lymphoma and represents less than 0.5% of colorectal neoplasms. Chemotherapeutical agents are gateway to disease remission and sometimes cure in most patients but surgery may be necessary in emergent situations

Clinicopathological features and management of colonic lipomas Case reports

Introduction: Colonic lipomas are benign tumors of adipose tissue that are often asymptomatic, but they may present with rectal bleeding or obstructive symptoms. These tumors are unique in that they are rarely encountered within the gastrointestinal system and can mimic malignant tumors in appearance. Surgical resection and endoscopic removal of tumors have been shown to be successful in their management. Patient concerns: In this report, we present 3 cases of colonic lipomas, 2 of which are located in the cecum and the other within the sigmoid colon. The presenting symptoms of the patients included abdominal pain, constipation, and dyspepsia. Diagnosis: Patients typically presented with anemia and an elevated C-reactive protein count. Colonoscopic and computerized tomography findings were used for diagnosis. Interventions: Hemicolectomy was performed, depending on the localization, and the pathologic specimens were consistent with lipoma. Outcomes: Surgical resection was curative in all patients. The postoperative period was uneventful in all patients and all patients are symptom-free and alive at 3 years follow-up. Conclusion: Colonic lipomas are benign mesenchymal tumors of the gastrointestinal system with a male predominance and are observed within the fourth to sixth decades of life. Various genetic abnormalities have been reported and they have been linked to the formation of intussusception. The squeeze sign on radiological imaging, cushion sign and tenting sign in colonoscopy, and naked fat sign during pathologic examination is helpful towards reaching a diagnosis. Surgical resection is the treatment of choice but minimally invasive endoscopic approaches have also been shown to be successful

Giant pedunculated liposarcoma of the esophagus

Background Liposarcoma is a common soft tissue neoplasm but its presence within the gastrointestinal system, especially the esophagus, is quite rare. It usually presents as an intraluminal or an intramural mass, with symptoms such as dysphagia and throat discomfort. Liposarcoma must be differentiated from benign tumors of the esophagus and managed appropriately. Case presentation In this report, we present the case of a 26-year-old woman who complained of dysphagia to liquids and solids and vague abdominal discomfort. The radiological modalities and endoscopic examination revealed a near-obstructing esophageal polypoid mass of 15 x 7.5 cm in size in the thoracal esophagus. A diagnosis of atypical lipomatous tumor/well-differentiated liposarcoma was made with morphological and immunohistochemical findings. Discussion Esophageal liposarcomas originate from primitive mesenchymal cells and are divided into several subtypes, with well-differentiated liposarcoma being the most common subtype. Various diagnostic tests are available, such as barium swallow, computerized tomography, magnetic resonance imaging, and esophagogastroduodenoscopy. Depending on the size and location of the tumor, minimally invasive endoscopic resection or more radical surgery such as esophagectomy can be performed. Conclusion Modern radiological imaging modalities have allowed better understanding and early diagnosis of lipomatous tumors of the esophagus. Optimal management varies, but minimally invasive techniques allow easy removal of the tumor stalk. However, more radical surgery such as esophagectomy is still performed. Due to its rarity, little is known about the prognosis of esophageal liposarcoma. Patients should be followed-up closely in the long term regarding recurrence

Primary neuroendocrine carcinomas of the breast and neuroendocrine differentiated breast cancers: Relationship between histopathological and radiological features

Purpose: The aim of this study was to investigate whole-breast imaging findings (mammography, ultrasonography (US), magnetic resonance imaging (MRI), clinical, and histopathological findings of primary neuroendocrine carcinomas of the breast (NEC) and neuroendocrine differentiated breast cancers (NEBC)
