Endometriosis is defined as the presence of endometrial-like glands and stroma outside the uterine endometrial lining. Endometrial tissue can be rarely identified on abdominal wall following numerous surgical or procedure scars, including cesarean section and hysterectomy. Cytological diagnosis of scar endometriosis is difficult, as it can be easily misinterpreted as benign spindle cells tumor. We report three cases where patients presented with a chief complaint of nodule in parietal abdominal wall adjacent to previous cesarean section scars and associated with history of cyclical pain. Provisional clinical diagnosis of desmoid tumor was made in one patient while the other two were diagnosed as endometriosis and they were referred for Fine needle aspiration cytology which revealed endometrial-like epithelial cells, stromal cells and hemosiderin-laden macrophages. Based on the cytological findings, diagnosis of Endometriosis arising in scar tissue was made which was confirmed on histopathology and wide local excision was done.
Primary malignant lymphomas of the salivary glands are rare, accounting for 2-5% of salivary gland tumors and 5% of extranodal lymphomas, frequently seen in the parotid gland. There are single case reports mentioned in the literature. Clinical presentation is not characteristic and the disease is often overlooked with delay in diagnosis and treatment. We are reporting a case of bilateral parotid gland lymphoma in a 55-year-old male, presented with bilateral enlarged parotids. Magnetic resonance imaging (MRI) showed bilateral enlarged parotid glands with multiple well-defined intraparotid lesions. Fine Needle Aspiration Cytology (FNAC) of both showed mixed population of lymphoid cells with large monocytoid cells with scant cytoplasm, anisonucleosis with prominent nucleoli, and numerous mitoses suggestive of non-Hodgkin's lymphoma (NHL). Histopathology showed sheets of large lymphoma cells destructing the salivary acini and infiltrating the periparotid fat. Immunohistochemistry (IHC) showed diffuse CD20 positivity, B-cell lymphoma 6 protein (Bcl-6) was focally positive and negative for cluster of differentiation (CD) 3, CD5, CD10, and Multiple myeloma oncogene-1 (MUM1) which led to the diagnosis of NHL-Diffuse large B cell type.
Chorangioma is the most common benign tumor of placenta, with an incidence of approximately 1%. Tumors larger than 5 cm are associated with maternal and fetal complications. We report four cases of chorangioma that were identified in mostly primigravida (75%) with a mean gestational age of 33 wks (Range 28-33 wks). All except one case, complete placenta was received with mean weight of 550 g (Range 400-800 g) and tumor size of 9.4 cm (Range 0.5-23 cm). Microscopy showed capillary proliferation resembling fetal vessels in enlarged villi covered by trophoblastic epithelium. Three cases had preterm delivery. One also presented with abruptio placenta and intrauterine fetal death. Because of limited documentation of cases and dismal prognosis of these pregnancies, especially with large chorangiomas, it's of utmost importance to correctly diagnose them with the aid of color Doppler flow. In this series, 75% of cases (3/4), babies survived probably due to small size of tumor and attainment of fetal maturity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
