The Great Mimicker: Cutaneous Metastatic Melanoma Presenting as a Non-resolving Pleural Effusion.

Although melanoma starts as a local disease, it can metastasize to other sites of the body including the lung, brain, liver, and intestines. However, pleural involvement is a rare presentation. Here, we present a case of a 57-year-old man with a history of stage IIA cutaneous melanoma, that relapsed 3 years after cutaneous resection, presenting with a non-resolving pleural effusion.

Metastatic Renal Cell Cancer With Pancreatic Mass.

A pancreatic mass is mostly discovered late in the course of the disease and is usually asymptomatic in the early stages. In rare cases, a pancreatic mass may be metastatic, and presentation may depend on the presence and locations of other metastasis or to the primary lesion. Renal cell cancer is the most common tumor presenting as metastatic pancreatic mass.

Epstein-Barr-virus-positive large B-cell lymphoma associated with breast implants: an analysis of eight patients suggesting a possible pathogenetic relationship.

Breast implant anaplastic large cell lymphoma (ALCL) is a T-cell neoplasm arising around textured breast implants that was recognized recently as a distinct entity by the World Health Organization. Rarely, other types of lymphoma have been reported in patients with breast implants, raising the possibility of a pathogenetic relationship between breast implants and other types of lymphoma. We report eight cases of Epstein-Barr virus (EBV)-positive large B-cell lymphoma associated with breast implants.

Hybrid verrucous-squamous cell carcinoma of the ovary with synchronous squamous cell carcinoma of the endometrium.

Verrucous carcinoma, a variant of well-differentiated squamous cell carcinoma, is usually described in the literature as arising in the oral cavity, skin, and larynx. The reports on verrucous carcinoma arising in the genital tract, usually originating in the vagina, vulva, or uterine cervix, are few. Verrucous carcinoma arising in the ovary has not been previously reported.
