Spectrum of Clinicopathological Deviations in Long-Segment Hirschsprung Disease Compared With Short-Segment Hirschsprung Disease: A Single-Institution Study.

Hirschsprung disease (HSCR) is a congenital disorder characterized by intestinal aganglionosis leading to pseudoobstruction. The majority of cases are limited to the rectum or rectosigmoid (S-HSCR). A variably longer segment can be affected (L-HSCR), which may show many deviations from S-HSCR.

Fine needle aspiration cytology of cystic primary adult granulosa cell tumor of the ovary: Potential diagnostic pitfalls with other cystic ovarian lesions.

Introduction: Fine needle aspiration(FNA) of cystic adult granulosa cell tumors(CAGCT) has been sporadically reported in the literature. We undertook a retrospective study to further elucidate the cytologic features on FNA material in order to avoid possible misinterpretation with other primary tumors of ovary.

Materials And Methods: During 1992 and 2014, FNA of five cases of CAGCT were recorded.

Asymptomatic diffuse "encephalitic" cerebral toxoplasmosis in a woman with systemic lupus erythematosus.

Classic cerebral toxoplasmosis typically presents with neurologic symptoms such as seizures and mental status changes and histological examination shows focal lesions with necrosis. However, in the diffuse "encephalitic" form, patients are asymptomatic with diffuse, inflammatory, non-necrotic lesions. Asymptomatic diffuse "encephalitic" toxoplasmosis has been reported only in four acquired immunodeficiency syndrome patients and one human immunodeficiency virus (HIV) negative patient with chronic lymphocytic leukemia.

Cytological features of Castleman disease: a review.

Introduction: Castleman disease (CD) is a benign lymphoproliferative disorder with hyaline vascular (HVCD), plasma cell (PC-CD), and mixed subtypes. Only HVCD lymph node cytomorphology has been described, mainly as case reports. We reviewed all CD subtypes.

Fine needle aspiration of secondary synovial sarcoma of the thyroid gland.

Synovial sarcomas (SS) of the head and neck region are extremely rare and arise in only 5% of cases. We present a case of secondary SS of the thyroid originally diagnosed as medullary carcinoma on fine needle aspiration (FNA). A 41-year-old man presented with several weeks of dysphonia and a left thyroid mass.
