Fibromatosis of the breast; another diagnosis of cancer like lesions: About 4 cases reports.

INTRODUCTION AND IMPORTANCE: Desmoid fibromatosis is a benign monoclonal fibroblastic tumor that was first reported in 1832 and arises from musculoaponeurotic structures. It is an uncommon tumor that can mimic breast carcinoma in both hits clinical and radiological presentation. This entity mainly affects patients in their fourth and fifth decades of life. CASE PRESENTATION: Our four patients were of young women in their 2nd and 3rd decade that consulted for masses of the breast. These lesions were suspicious for malignancy in both their clinical and radiological features despite not having any family history of breast carcinoma. CLINICAL DISCUSSION: Only histology provides the diagnosis, it is locally invasive, non-metastatic but with a high potential of recurrence and the sole treatment is complete and wide local excision with clear margins. CONCLUSION: Although it is a rare clinical scenario, the presence of an unusual breast or chest wall tumor such as a desmoid tumor should be considered when obvious breast changes and history do not correlate with routine diagnostic measures.

Ruptured mature ovarian teratoma: A case report.

INTRODUCTION: Dermoid cysts, or also known as mature cystic teratomas, are one of the most common benign ovarian tumors. Spontaneous rupture of this tumor is rare and can be suspected on imaging. CASE REPORT: we report a case of ruptured mature ovarian teratoma. A 21 years old previously healthy woman presented with recurrent pelvic pain, the diagnostic of rupture was made by imaging. The patient underwent surgery with a good follow up. DISCUSSION: Dermoid cysts are the most common benign ovarian neoplasm and its rupture is rare due to its thick capsule. Imaging has a major role in the diagnosis of dermoid cyst and in the detection of its rupture. CT scan is the most requested modality imaging especially in acute abdominal pains. MRI can performed for further characterization. CONCLUSION: the aim of the study is to report a new case of ruptured mature ovarian teratoma and to describe the imaging signs suggesting dermoid cysts rupture.

Gastrointestinal stromal tumor of the ampulla of Vater: A case report and literature review.

INTRODUCTION: Gastrointestinal stromal tumors (GISTs) usually develop in the stomach and small intestine and only rarely occur in the ampulla of Vater (AV). CASE PRESENTATION: We report a case of a GIST of the AV. A 21-year-old, previously healthy woman presented with a three-month history of epigastric pain, jaundice and weight loss. The diagnosis of a tumor in the second part of the duodenum was made by the computed tomography. The patient underwent pancreatoduodenectomy, the operative specimen revealed an intermediate risk group of GIST and thus, the patient didn't take adjuvant therapy. DISCUSSION: GIST rarely develops in the duodenal ampulla region and it has no specific symptomatology. Radiological investigations play an important role in the diagnosis of Stromal Tumor of the Ampulla of Vater (STAV) mainly computed tomography because STAV has a large size in the majority of cases contrary to adenocarcinoma. CONCLUSION: The aim of this study is to report a new case of STAV combined with a systematic review of reported cases published in peer-reviewed journals.

Acute pancreatitis secondary to spontaneous intramural duodenal hematoma: A case report and a review of the literature.

INTRODUCTION: Intramural duodenal hematoma is a rare entity, often secondary to traumatic origin, but more rarely spontaneous due to blood flow disorders, especially in the context of anticoagulant therapy. CASE PRESENTATION: We report the case of a 66-year-old woman under anticoagulant treatment for atrial fibrillation, who was diagnosed with acute pancreatitis secondary to a spontaneous duodenal hematoma. The evolution was favorable under medical treatment. DISCUSSION: Intramural duodenal hematoma is frequently associated with abdominal pain and hematemesis, more rarely, it can be responsible for an acute pancreatitis, which is considerate as an unusual complication. We report here a case of duodenal hematoma revealed by acute pancreatitis along with a review of the literature since 2011. CONCLUSION: Monitoring of patients on oral anticoagulants helps prevent the occurrence of IDH and avoid its complications, which can be fatal.

Masseter idiopathic calcinosis circumscripta: A rare condition.

Calcinosis is defined as a biomineralization occurring in soft tissues leading to ectopic calcification. Isolated and localised calcification in a muscle is rare, and it is called calcinosis circumscripta in opposition to calcinosis universalis wich is seen in juvenile dermatomyositis and polymyositis. According to laboratory findings and clinical history, calcinosis circumscripta can be metastatic, dystrophic or idiopathic. Masseter muscle is rarely involved. Pre-operative diagnosis of masseter idiopathic calcinosis is a challenge because of many differential diagnosis. Here, we report a case of 22 years old women presented with swelling over left middle third of her face. Clinical history, morphologic and laboratory examinations helped considering such a rare diagnosis.
