Recognizing the distinct cytomorphologic features of solid pseudopapillary neoplasm of the pancreas.

Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare low-grade malignant tumor with an indolent clinical course and a favorable prognosis that is most commonly seen in young women of reproductive age. We present a case of SPN in a middle-aged man, diagnosed on a limited cytology specimen. Interestingly, this tumor has unique cytomorphologic findings in fine needle aspiration cytology smears, which help distinguish it from other pancreatic lesions.

A seventeen-year-old female with hepatosplenic T-cell lymphoma associated with parvoviral infection.

Hepatosplenic T-cell lymphoma (HSTL) is rare, being derived from cytotoxic T-cells, and manifests as an extranodal systemic lymphoma. We present an unusual case of a seventeen-year-old female, with no significant prior medical history, presenting with a hepatosplenic T-cell lymphoma. The diagnosis was confirmed by histological examination, immunohistochemisty, and flow cytometry.

Three patients with both Hodgkin's lymphoma and Castleman's disease: Clinicopathologic correlations and lack of association with HHV-8.

Background: The relationship between Hodgkin's lymphoma (HL) and plasma cell-type Castleman's disease (PCD) has been well documented. There have been over 20 cases reported in the literature and nearly all of them were either diagnosed concurrently, or were initially diagnosed as PCD and upon review were found to have interfollicular HL. Human herpes virus type 8 (HHV-8) is present in about 40% of cases with PCD.

A thirteen year old female with primary T-cell rich B-cell lymphoma of bone masquerading as chronic recurrent multifocal osteomyelitis.

Primary lymphoma of the bone (PLB) accounts for 2% of all non-Hodgkin's lymphomas, and until recently it had not been well characterized in literature. Most cases present in adulthood (average age 50), with localized painful lesions in the long bones, cranium, or axial skeleton.We describe a case of multifocal PLB in an adolescent female.

Laparoscopic Roux-en-Y gastric bypass in patients with congenital malrotation.

Bariatric surgery is the only solution for morbidly obese individuals who desire to lose weight and maintain it and have failed to do so by non-surgical means. As the incidence of morbid obesity rises, laparoscopic Roux-en-Y gastric bypass (LRYGBP) is increasingly performed. With the increase in bariatrics, the chances of discovering aberrant anatomy at the operating-table also increase.

Pancreatic mass of unusual etiology: case report of metastatic disease after a prolonged lag phase.

Although not a typical site, the pancreas does occasionally harbor metastatic disease. Management of these metastases differs from the management of conventional primary cancers. Our case is one of an 85-year-old female presenting with obstructive jaundice and whose workup revealed a pancreatic mass.
