Cutaneous clues to renal cell carcinoma: hereditary leiomyomatosis and renal cell carcinoma.

We present a case of a 33-year-old female who was incidentally found to have cutaneous leiomyomata during a routine skin examination. Further history revealed that she also suffered from uterine fibroids and that her mother had died at an early age from renal cell carcinoma. This case serves as a reminder of the often-subtle cutaneous clues, as well as the importance of a multidisciplinary approach, for early diagnosis of potentially fatal conditions.

Paraneoplastic pemphigus and Castleman's disease in the setting of herpes simplex virus infection.

A 14-year-old girl presented with a 3-week history of mucosal erosions, injected conjunctiva, dehydration, and respiratory distress. She had been treated with intravenous acyclovir for herpes simplex infection with positive herpes simplex virus immunoglobulin M and immunoglobulin G. Physical examination and imaging revealed a large abdominal mass. Incisional biopsy was obtained, and pathology demonstrated angiofollicular hyperplasia with hyalinized germinal centers and Castleman's syndrome-like features. Based on the mucosal erosions, herpes simplex virus serology and positive herpes simplex virus-1 direct fluorescent antibody, Castleman's disease secondary to overwhelming herpes simplex virus infection was the initial impression. The poor response to antivirals and subsequent development of a bullous eruption on the hands resulted in dermatology consultation. Skin biopsy was obtained from a bullae and revealed suprabasilar acantholysis with necrosis as well as upper dermal, perivascular, and interface infiltrate of lymphocytes and eosinophils. No viropathic changes were present. Direct immunofluorescence was significant for immunoglobulin G deposition intercellularly and along the dermoepidermal junction and focal trace C3 deposition along the dermoepidermal junction consistent with paraneoplastic pemphigus, later confirmed by indirect immunofluorescence. We report this case of paraneoplastic pemphigus secondary to Castleman's syndrome confounded by herpes simplex virus-1 positive mucosal erosions.

Factors associated with physician discovery of early melanoma in middle-aged and older men.

OBJECTIVE: To determine factors associated with physician discovery of early melanoma in middle-aged and older men. DESIGN: Survey. SETTING: Three institutional melanoma clinics. PARTICIPANTS: A total of 227 male participants (aged > or =40 years) with invasive melanoma who completed surveys within 3 months of diagnosis. Intervention Survey. MAIN OUTCOME MEASURES: Factors associated with physician-detected thin melanoma. RESULTS: Patients with physician-detected melanoma were older, 57% were 65 years or older compared with 34% for other-detected (odds ratio [OR], 2.57; 95% confidence interval [CI], 1.19-5.55) and 42% for patient-detected melanoma (P = .07). Physician-detected melanoma in the oldest patients (aged > or =65 years) had tumor thickness equal to that of self-detected melanoma or melanoma detected by other means in younger patients. Back lesions composed 46% of all physician-detected melanoma, 57% of those detected by other means, and 16% of self-detected lesions (physician- vs self-detected: OR, 4.25; 95% CI, 1.96-9.23). Ninety-two percent of all physician-detected back-of-the-body melanomas were smaller than 2 mm compared with 63% of self-detected lesions (P = .004) and 76% of lesions detected by other means (P = .07). CONCLUSIONS: Skin screenings of at-risk middle-aged and older American men can be integrated into the routine physical examination, with particular emphasis on hard-to-see areas, such as the back of the body. "Watch your back" professional education campaigns should be promoted by skin cancer advocacy organizations.

Melanoma in middle-aged and older men: a multi-institutional survey study of factors related to tumor thickness.

OBJECTIVES: To identify factors related to the detection of melanoma and to determine those that differ between thinner vs thicker tumors in middle-aged and older men. DESIGN: Survey. SETTING: Three institutional melanoma clinics. PARTICIPANTS: Men 40 years or older who had newly diagnosed invasive melanoma. MAIN OUTCOME MEASURES: Differences in melanoma awareness, skin examination practices, discovery patterns, and social/medical care factors relative to tumor thickness. RESULTS: Two hundred twenty-seven men completed surveys within 3 months of melanoma diagnosis; 57 (25.1%) had thicker tumors (>2.00 mm). Thicker tumors were associated with nodular histologic features (43.9%), a lack of atypical nevi, having less than a high school education, and patient vs physician (dermatologist or nondermatologist) detection. Knowledge of melanoma (P = .007), attention to skin cancer detection information (P = .02), an interest in health topics (P = .003), and knowing the importance of physician skin examination (P = .05) were more common in those with thin tumors. Tumor thickness did not correlate with age, anatomic location, marital/cohabitation status, prior skin cancer, or sun sensitivity. Overall patient awareness of melanoma warning signs, skin self-examination practices, and Internet use were poor (<20%, <50%, and <14%, respectively). CONCLUSIONS: Physician discovery, the patient's higher level of education and detection-promoting awareness and attitudes, and the presence of clinically atypical nevi were related to thinner melanomas. Innovative outreach strategies and novel educational campaigns incorporating these factors, coupled with sharper messages regarding the importance of physician screening, are needed to improve early detection in middle-aged and older men.

Evaluation of digital dermoscopy in a pigmented lesion clinic: clinician versus computer assessment of malignancy risk.

Digital dermoscopy systems employ computer-based algorithms to quantitate features of pigmented skin lesions (PSLs) and provide an assessment of malignancy risk. We evaluated interobserver concordance of PSL malignancy risk between a pigmented lesion specialist and an artificial neural network (ANN)-based automated digital dermoscopy system. While digital dermoscopy provides a reliable means of image capture, storage, and comparison of PSLs over time, the ANN algorithm requires further training and validation before the malignancy risk assessment feature can be widely used in clinical practice.
