Primary Extranodal Skeletal-Muscle Non-Hodgkin B Cell Lymphoma: Clinical Presentation and Diagnostic Approach.

Primary extranodal non-Hodgkin lymphomas that involve skeletal muscles (PSML) are infrequent with non- specific features or symptoms. Therefore, their diagnosis can be immensely convoluted since they mimic other soft tissue tumors and diseases (34). In this study, the case of a 61-year-old male patient, who presented with a history of a 6-week left thigh oedema and concomitant pain in our Emergency Department, is discussed. The patient was initially reviewed in another institution; the results of imaging studies (ultrasound scan) were consistent with deep vein thrombosis (DVT).Despite treatment, the patient's pain and swelling was exacerbating, which forced him to visit our hospital. Magnetic resonance imaging (MRI) revealed a diffused mass in his right thigh, while fine needle aspiration cytology (FNAC) yielded a diagnosis of B-cell lymphoid hyperplasia. The patient was then referred to a tertiary cancer treatment center for further management.

Inflammatory pseudotumour of the colon.

Introduction A colorectal inflammatory myofibroblastic tumour (IMT) is a rare but benign entity masquerading as a malignant tumour. Although the lung is considered the most common site of occurrence, IMTs may arise in diverse extrapulmonary locations. We describe a case of a colonic IMT in a patient who presented in the emergency setting. Case History A 77-year-old man was admitted at our emergency department with acute abdominal pain. Physical examination revealed vague tenderness of the lower abdomen and non-palpable masses. Preoperative evaluation revealed a mass in the right lower quadrant of the abdomen, possibly originating from the terminal ileum, 1-2cm from the caecum. Owing to the clinical impression of a potentially malignant lesion, the patient underwent subtotal colectomy and omentectomy. The pathology report suggested the morphological and immunohistochemical features were more compatible with a colonic IMT. Conclusions A colorectal IMT is a rare clinical entity that can easily mimic a highly malignant tumour and cannot be distinguished clinically or radiologically. An accurate diagnosis is based on histological examination and surgical resection is therefore usually required.
