Staged Excision for Lentigo Maligna and Lentigo Maligna Melanoma: Analysis of Surgical Margins and Long-term Recurrence in 68 Cases from a Single Practice.

Introduction: Lentigo maligna is a form of in situ melanoma that occurs commonly on sun-exposed skin of middle-aged to elderly adults. Margin-control surgery offers the highest cure rate for lentigo maligna/lentigo maligna melanoma.

Materials And Methods: Charts from the authors' private office from the 20-year period from January 1986 to December 2005 were reviewed to identify patients with histologically confirmed lentigo maligna or lentigo maligna melanoma treated by staged excision.

Lymphoplasmacytic plaque in children: a report of two new cases with review of the literature.

Lymphoplasmacytic plaque in children has been proposed as a rare, emerging clinicopathologic entity characterized by solitary, extratruncal, asymptomatic papules and plaques that are typically found in healthy young Caucasian females. Biopsy of these lesions reveals a dermal lymphoplasmacytic infiltrate with or without epithelioid granulomas. Two unique patients with lymphoplasmacytic plaque in children are presented in this report, including a 26-month-old female with a lesion on her finger, who represents both the youngest described patient and the first documented with a finger lesion, as well as a 17-year-old young woman with a left thigh lesion, who represents the patient with the longest clinically and histopathologically observed lesion to date.

Autoimmune progesterone dermatitis. Case report with histologic overlap of erythema multiforme and urticaria.

Background: Autoimmune progesterone dermatitis is a rare eruption that recurs monthly as progesterone levels peak during the menstrual cycle. Clinical and histologic features are variable, and the eruption is thought to represent a hypersensitivity response to endogenous progesterone.

Methods: We present the case of a 38-year-old woman with a pruritic intermittent facial eruption of 18 months' duration that recurred predictably in the days surrounding menses.

Folliculotropic mycosis fungoides responding to bexarotene gel.

Folliculotropic mycosis fungoides (FMF) is an uncommon and potentially aggressive form of cutaneous T cell lymphoma (CTCL). Phototherapy, radiotherapy, and systemic chemotherapy are the most commonly employed treatment options, but may have limited success and common adverse reactions. Bexarotene gel is a topical retinoid X receptor (RXR) agonist with activity on the follicular unit that has not been previously reported in the management of FME The case of a 73-year-old male with FMF that responded to bexarotene gel is presented.

Staged excision versus Mohs micrographic surgery for lentigo maligna and lentigo maligna melanoma.

Background: Lentigo maligna (LM) is a relatively common tumor with increasing prevalence and substantial morbidity. A variety of treatment modalities are available, though margin-control surgery offers the highest cure rate. We were interested in comparing long-term outcomes of Mohs micrographic surgery (MMS) versus staged excision with permanent sections (SE) for treating LM or LM melanoma (LMM).
