Persistent serpentine supravenous hyperpigmented eruption in lepromatous leprosy after minocycline.

Persistent serpentine supravenous hyperpigmented eruption (PSSHE) is a peculiar patterned eruption characterised by hyperpigmented streaks following the superficial venous network on the skin. Unlike the superficial thrombophlebitis, it is characterised by underlying vessels that are patent. It has been described most commonly after injection of chemotherapeutic drugs. We describe a 40 year old man with lepromatous leprosy who developed PSSHE subsequent to starting modified multidrug therapy--multibacillary regimen in the form of minocycline and ofloxacin.

Long-term follow-up and epidemiological trends in patients with pretibial myxedema: an 11-year study from a tertiary care center in northern India.

INTRODUCTION: Pretibial myxedema (PTM) is a rare manifestation of Graves' disease. There is paucity of data regarding long-term follow-up and response to treatment in PTM. MATERIALS AND METHODS: Retrospective study wherein 30 patients of PTM presenting during 2001-2011 attending dermatology and endocrinology outpatient departments were analyzed. RESULTS: Among 30 patients with PTM, 12 were males and 18 females with a ratio of 1 : 1.5 males/females. Four morphological forms were identified: plaques (18 patients), diffuse non-pitting edema of both lower legs (five), nodules (five), and elephantiasis lesions (two). Eighty percent were diagnosed with hyperthyroidism before the development of dermopathy. Twenty-six patients presented with ophthalmopathy. Fourteen patients with plaque had an excellent response to topical clobetasol propionate ointment and attained complete resolution by 3.6 years. Out of 16 patients treated with combination therapy, which included nine treated with topical corticosteroids/intralesional triamcinolone and seven treated with oral, intralesional, and topical corticosteroids, nine attained complete resolution in the lesions by 3.4 years, and none relapsed anytime during four years of post-treatment follow-up. However, the remaining patients (elephantiasis and diffuse forms) failed to achieve complete resolution. CONCLUSIONS: Plaques and nodules are common variants with a favorable clinical response to topical and intralesional corticosteroid; elephantine and diffuse forms responded poorly to therapy. Studies analyzing larger cohorts of patients with PTM and their long-term follow-up are limited, hence more such studies are required.
