Primary pulmonary epithelioid inflammatory myofibroblastic sarcoma: a rare entity and a literature review

Epithelioid inflammatory myofibroblastic sarcoma (EIMS) is an aggressive subtype of inflammatory myofibroblastic tumor (IMT) harboring anaplastic lymphoma kinase (ALK) gene fusions and is associated with high risk of local recurrence and poor prognosis. Herein, we present a young, non-smoking male who presented with complaints of cough and dyspnoea and was found to harbor a large right lower lobe lung mass. Biopsy showed a high-grade epithelioid to rhabdoid tumor with ALK and desmin protein expression. The patient initially received 5 cycles of crizotinib and remained stable for 1 year; however, he then developed multiple bony metastases, for which complete surgical resection was performed. Histopathology confirmed the diagnosis of EIMS, with ALK gene rearrangement demonstrated by fluorescence in situ hybridization. Postoperatively, the patient is asymptomatic with stable metastatic disease on crizotinib and has been started on palliative radiotherapy. EIMS is a very rare subtype of IMT that needs to be included in the differential diagnosis of ALKexpressing lung malignancies in young adults.

Efficacy of magnetic resonance imaging in assessment of myometrial invasion of carcinoma endometrium

Background: Endometrial carcinoma is the fourth most common cancer in females and the most common malignancy of the female reproductive tract. The prognosis of endometrial carcinoma depends on a number of factors, including stage, depth of myometrial invasion, lympho-vascular invasion, nodal status and histologic grade. Preoperative assessment with MRI is essential for planning surgery and lymph node sampling. The objectives of this study were to determine the myometrial invasion of endometrial carcinoma by MRI and to obtain histopathology in surgically resected specimen, to compare the MRI findings of myometrial invasion in endometrial carcinoma with histopathology in respectable cases.Methods: Authors analyzed 41 cases in whom, histopathological diagnosis of carcinoma endometrium was established by means of pre-treatment biopsy. Consenting patients were taken up for preoperative MRI FIGO staging. MR images were reviewed for parameters like depth of myometrial invasion. Further surgical management followed by histopathological FIGO staging was done.Results: The study showed MRI was highly sensitive and specific tool for identifying depth of myometrial invasion, cervical invasion, serosal invasion, vaginal and parametrial invasion.Conclusions: There was statistically significant difference between histopathological and MRI assessment of local invasion of endometrial carcinoma.
