RESUMEN
Syringomas are benign tumors derived from the intraepidermal portion of eccrine sweat ducts. They usually occur on the periobital area, but have also been found on the scalp, forehead, cheeks, axillae, abdomen, extremities, genitalia, and buttocks. We describe a patient with an unusual presentation of unilateral syringoma of the face associated with hyperthyroidism.

BACKGROUND: Behçet's disease (BD) is a multisystemic inflammatory disorder found in individuals with a particular genetic background. Hemostatic studies in BD support an imbalance towards a prothrombotic state at different levels. Lipoprotein (a) (Lp(a)) has atherogenic and thrombogenic properties. It is mostly under genetic regulation. We investigated the possible relationship between Lp(a) and BD. METHODS: Forty patients diagnosed with BD and 40 healthy controls were enrolled. The clinical characteristics of the patients were recorded. Serum total cholesterol, high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), apolipoprotein A1, apolipoprotein B, and Lp(a) levels of the two groups were assessed and compared statistically. RESULTS: All patients (100%) had oral aphthous ulcers. Thirty (75%) had genital ulceration, 37 (92.5%) had either erythema nodosum or papulopustular lesions, and 10 (25%) had eye involvement. Twelve (30%) had a positive pathergy test. Four (10%) had vascular involvement. The Lp(a) level of the patient population was 19.6+/-18.8 mg/dL. This level was higher than that of the controls, but not statistically significant. The Lp(a) levels of the four patients with vascular complications were within normal limits. CONCLUSIONS: Lp(a) is of interest, as it is a genetically determined parameter that was found to be high in BD patients in our study group. The levels were independent of thrombotic complications, perhaps suggesting a different role for this lipoprotein in the etiopathogenesis of BD. Further studies with a larger number of patients are essential to discover the exact role of Lp(a) in BD.

PURPOSE: This study was designed to investigate the local subcutaneous fat thickness in sacrococcygeal pilonidal disease. METHODS: Subcutaneous fat thickness was measured by ultrasonography in 125 patients with sacrococcygeal pilonidal disease and 125 age-matched, body mass index-matched and gender-matched controls. RESULTS: The sacrococcygeal subcutaneous fat thickness was 14.4 +/- 2.9 mm, 18.3 +/- 3.1 mm, and 22 +/- 2.2 mm, respectively, in normal, overweight, and obese patients with sacrococcygeal pilonidal disease and 9.1 +/- 3.1 mm, 11.3 +/- 2.6 mm, and 20 +/- 1.8 mm, respectively, in normal, overweight, and obese controls. Sacrococcygeal fat was significantly thicker in normal and overweight patients with pilonidal disease compared with controls with same body mass index (P< 0.01). There were no significant differences in fat thickness between obese patients and obese controls (P > 0.05). CONCLUSIONS: Sacrococcygeal fat thickness, as a local factor, is closely associated with pilonidal disease.

Bacillus anthracis infection can lead to necrosis in tissues and may manifest as a fatal disease in human beings. The authors present a patient with a large area of skin necrosis on the dorsum of the hand that was reconstructed with a reverse flow-through radial forearm flap, and they discuss the relevant literature. To the authors' knowledge, this is the first published report of such extensive necrosis resulting from anthrax limited to the extensor retinaculum of the hand.
