Unlabelled: Melanocytic nevi are the most common tumors of the conjunctiva, accounting for 28% of all neoplastic lesions. These tumors, despite their benign behavior, share some atypical histological features with nevi found in other anatomic sites like the genital and acral regions, globally designated as nevi with site-related atypia. Moreover, in children and adolescents, rapidly growing conjunctival nevi show sometimes worrisome histological patterns in association with a prominent inflammatory infiltrate that may lead to diagnostic problems. In this paper we describe a juvenile compound nevus characterized by marked melanocytic atypia and severe inflammation, which can be considered a rare case of juvenile conjunctival atypical nevus. The final diagnosis relied on morphological and immunohistochemical characterization of the large epithelioid melanocytic cells, and on the results of FISH analysis.

Peribronchiolar metaplasia is an uncommon lesion characterized by fibrosis and bronchiolar epithelial cell proliferation along the peribronchiolar alveolar walls, primarily in response to bronchiolar and peribronchiolar injuries. Peribronchiolar metaplasia usually appears as ground glass nodules or sub-solid nodules on computed tomography. However, we present an exceptional case of peribronchiolar metaplasia that appeared as a solitary solid nodule on computed tomography.

Celiac disease (CD) is a chronic illness. Blood testing for tissue transglutaminase antibodies is the initial screening test for the diagnosis of CD, and upper gastrointestinal endoscopy and duodenal/jejunal biopsy are used to confirm CD. Intussusception (IS) is the process in which a proximal segment of the bowel invaginates through the lumen of a distal segment.

We report the case of a Hispanic male whose conjunctival atypical fibroxanthoma (AFX) grew very large, with intraocular as well as extraocular muscle extensions, and was treated with exenteration. A 50-year-old male presented with a one-month history of foreign-body sensation in his left eye. The initial examination revealed an erythematous, vascularized, pedunculated lesion arising from the left eye conjunctiva.
