Background: Phaeohyphomycosis is a very rare fungal infection, which is one of more usual complications in immunocompromised and/or traumatic patients, has never been reported especially in a cytological field. We describe a first case of subcutaneous phaeohyphomycosis caused by Exophiala xenobiotica (E. xenobiotica) in a poorly controlled diabetic patient, and in which a correct cytological diagnosis of phaeohyphomycosis was possible to conclude.

Background: Recent studies analyzed the impact of Merkel cell polyomavirus (MCPyV) on the prognosis of Merkel cell carcinoma (MCC) patients. No data on specific morphological clinical differences of MCPyV+ or MCPyV- are currently available neither on the possible prognostic implication of different clinical presentation of MCC.
Objectives: 1) to describe clinicopathological characteristics of MCC patients and the prevalence of MCPyV infection in an Italian cohort of patients; 2) to define possible differences in clinicopathological and prognostic features among MCPyV+ and MCPyV- MCCs.
The relationship between spontaneous cystic degeneration and pseudocapillarization in sinusoids in the liver of aged Sprague-Dawley rats.

Cystic degeneration (CD) in the liver is a cyst-like lesion composed of one or more pseudocysts lacking lining cells, occurring spontaneously in rats older than 12 months, with a male predilection. In this study, 32 CDs were identified in 23 out of 104 non-treated, control male Sprague-Dawley rats from two combined chronic toxicity and carcinogenicity studies with agrochemicals. They were examined histologically, histochemically, and immunohistochemically to assess the pathogenesis and pathological significance of CD, focusing on pseudocapillarization in aged rat liver.

A 39-year-old woman presented a saucer-shaped mass in the left upper eyelid and underwent the extirpation at local anesthesia. Pathologically, collagen fibers, capillaries, small vessels, and CD34-positive spindle cells were dispersed among mature adipose tissues, indicative of spindle cell lipoma. Long-lasting cyst-like eyelid masses would be usually dermoid cysts, and spindle cell lipoma would be listed as a rare pathological diagnosis in differential diagnoses of cyst-like lesions in the upper and lower eyelid.

Introduction: This article presents the fourth detection of macroscopic cystic lesions due to sarcocystosis in domestic pigs during routine meat inspection worldwide, and the first molecular detection of in a domestic pig in Poland. Pigs can become intermediate hosts for by accidental ingestion of oocysts or sporocysts present in food or water contaminated by the faeces of canids (definitive hosts).
Material And Methods: The affected swine showed no clinical symptoms such as weight loss, dermatitis or dyspnoea suggesting sarcocystosis.
