Nodular hidradenoma is an uncommon cutaneous adnexal tumor arising from sweat glands. In the skin, it usually presents as a solitary dermal nodule; excision is curative in most cases. In rare instances, it may present as a breast mass and can mimic breast carcinoma clinically and radiologically, causing diagnostic dilemmas for the treating physician and pathologist. Herein, we discuss a case of nodular hidradenoma in a 20-year-old Hispanic woman as a rapidly growing mass in the breast that mimicked breast carcinoma...

Waldenström macroglobulinemia (WM) is a form of lymphoplasmacytic lymphoma that can cause hyperviscosity syndrome due to unchecked monoclonal antibody production. Some patients are also found to have associated cryoglobulinemia, which can cause systemic complications including vasculitis, renal disease, and pulmonary complications. Cryoglobulins can also serve as a source of interference with various laboratory assays. Therapeutic plasma exchange (TPE) is one of the recommended treatment modalities to manage hyperviscosity...
