Concomitant hypertrophic lichen planus and squamous cell carcinoma: Clinical features and treatment outcomes.

Background: Patients with hypertrophic lichen planus (HLP) and squamous cell carcinoma (SCC) diagnoses present clinicians with diagnostic and disease management challenges.

Objective: To better define the clinical and treatment outcomes of patients with concomitant diagnoses of HLP and SCC.

Methods And Materials: A retrospective review was performed from January 1, 2008, to July 31, 2015, at Mayo Clinic.

Acquired lymphangiectasia (lymphangioma circumscriptum) of the vulva: Clinicopathologic study of 11 patients from a single institution and 67 from the literature.

Background: Acquired lymphangiectasia of the vulva (ALV) is a rare condition thought to be secondary to pelvic lymphatic obstruction. Although benign, this entity often occurs after previous malignancy and can be confused with conditions such as genital warts. We sought to clarify the clinicopathologic features of ALV by studying affected patients from our institution and from the existing literature.

Cutaneous microemboli from hydrophilic polymer after endovascular procedures.

Background: Multiple devices and coatings assist with endovascular insertion of sheaths, catheters, and guide wires. Hydrophilic polymer coatings, a common component of endovascular surgical devices, reportedly cause microvascular obstruction and embolization, with various sequelae in organs and soft tissue.

Objective: We sought to describe clinical and histopathologic features of cutaneous manifestations of hydrophilic polymer gel emboli.

Incidence of Merkel cell carcinoma in Olmsted County, Minnesota: a population-based study.

Background: Merkel cell carcinoma (MCC) is a rare, aggressive, often cutaneous malignancy. The incidence has been estimated from national registries in the USA and elsewhere, and data indicate variations depending on the region studied. The objective of this study was to determine the incidence of MCC in Olmsted County (MN, USA).

Cutaneous T-cell lymphoma in patients with chronic lymphocytic leukemia: clinical characteristics, temporal relationships, and survival data in a series of 14 patients at Mayo Clinic.

Background: We examined the course of cutaneous T-cell lymphoma (CTCL), which has been associated with chronic lymphocytic leukemia (CLL) in patients with CLL.

Materials And Methods: A search was conducted of the master diagnosis index at our institution to identify patients with both CLL and CTCL from 1980 to 2010. A retrospective chart review was then conducted.

Mycobacterium fortuitum infection following adalimumab treatment for psoriasis and subsequent complication-free treatment with alternate TNF-a blockers.

Tumor necrosis factor-a (TNF-a) inhibitors, such as adalimumab, are often used to treat psoriasis and psoriatic arthritis. While it is well known that these agents increase the risk of reactivation tuberculosis, recent evidence suggests that the risk of other nontuberculous mycobacterial (NTM) infections is on the rise. We report cutaneous Mycobacterium fortuitum in a 60-year-old woman with psoriasis who had been receiving adalimumab therapy for psoriatic arthritis for six months.
