Secretory carcinoma (SC) of salivary gland, previously known as mammary analogue secretory carcinoma, is a rare low-grade malignancy harboring a diagnostic ETV6-NTRK3 gene fusion. SC of salivary gland shares histopathological, immunohistochemical and genetic characteristics with SC of the breast. There are several previous cytomorphological characterizations of SC of salivary gland reported in the literature.

We report a case of acral myxoinflammatory fibroblastic sarcoma (AMIFS) in a woman who presented with a longstanding mass on the dorsum of her left foot. The diagnosis was suggested by fine needle aspiration cytology and established by wide excision.

Herein is described our clinical experience using Cervista HPV HR, a testing platform recently approved by the US Food and Drug Administration for clinical use. Using data from a high-volume commercial laboratory, a retrospective analysis of cytologic and Cervista HPV HR test results from 56,501 samples was performed, and an indirect comparison was made with previous experience with 53,008 samples tested using the Hybrid Capture 2 platform.

Given the comparatively good prognosis of CASTLE, it is crucial to distinguish this neoplasm from other more aggressive thyroid neoplasms that can have similar or overlapping cytomorphological features. However, there is little information about the cytomorphology of CASTLE available in the literature.

The association of cell surface GRP78 with other proteins such as MTJ1 stimulates cell proliferation. In this study, we characterized the pattern of expression of GRP78 and MTJ1 in invasive primary cutaneous melanomas and analyzed the relationships between the pattern of expression and various clinicopathological parameters.

Although fairly well characterized histologically, with a distinct immunophenotype, it remains under-recognized, with as many as one third of cases initially misdiagnosed. This is often due to a failure to consider the entity.

Methods: Clinical and pathological findings are presented in a patient with an orbital tumor.
Results: Orbital magnetic resonance imaging in a 51-year-old female revealed a heterogeneously enhancing right orbital mass.
We describe radiologic findings in 2 patients and 18-fluoro-deoxy-glucose positron emission tomography/computed tomography findings in 1 patient who developed Kaposi sarcoma of the lung after bilateral lung transplantation. These findings included lung nodules, mediastinal or hilar lymphadenopathy, and pleural fluid.
