(ERYTHEMA NODOSUM LEPROSUM) the Term
? THE HISTOPATHOLOGY OF ACUTE PANNICULITIS NODOSA LEPROSA (ERYTHEMA NODOSUM LEPROSUM) w. J. PEPLER, M.B., Ch.B. Department of Pathology, South African Institute for Medical Research, Johannesburg R. KOOIJ, M.D. Westfort Institution, Pretoria AND J. MARSHALL, M.D. University of Pretoria, Pretoria The term "erythema nodosum leprosum" has frequently appeared in the literature on leprosy since the 1930's, apparently popularized by the Japanese (9). The occurrence of "erythema nodosum" in leprosy had previously been noted at the end of the nineteenth century by Brocq (6) and by Hansen and Looft (8), but the term seems to have fallen into disuse. As will become clear from our clinical and histological descriptions of the phenomenon commonly known as erythema nodosum leprosum, we believe the title to be a misnomer. We suggest that it would be more accurate to call it panniculitis nodosa leprosa (P.N.L,). This condition is commonly confused with acute lepra reaction, both processes being referred to as "acute reactions"; but a sharp line of distinction must be drawn between them. P.N.L. occurs only in patients with lepromatous leprosy as an acute, subacute or chronic skin eruption, with or without fever. It is characterized by showers of dusky red nodules, 0.5 to 2 cm. in diameter, on the extensor surfaces of the limbs, on the face, and, less often, on the trunk. The number of lesions appearing in an attack varies from a few to several hundreds, and they sometimes coalesce to form plaques. The nodules may be painful, and they are usually tender to touch. -

Langley MD, Amanda Webb BSc See related clinical image by Beleznay and colleagues, available at www.cmaj.ca 20-year-old female university student presented with a two-month history A of asymptomatic pigmentation in a net-like distribution, isolated to the front thighs (Figure 1). She was otherwise healthy, apart from having recently completed a six- month course of isotretinoin for acne. She had no history of trauma to the front of the thighs, and her only medication was an oral contra- ceptive. On further questioning, however, she admitted to longstanding daily use of a laptop computer positioned atop her thighs. This appearance is consistent with a diag- nosis of erythema ab igne.

"Abstract" "Comparison of Prevalence and Number of Lentigo, Freckle, Melanocytic Nevus and Other Neavus Lesions in Women with and Without Melasma"
"Abstract" "comparison of prevalence and number of lentigo, Freckle, melanocytic nevus and other neavus lesions in women with and without melasma" Introduction: Melasma is applied to a pattern of pigmentation seen mainly in women, and may be regarded as a physiological change in pregnancy. the hypermelanosis affects the upper lip, cheeks, forehead and chin and becomes more apparent following sun exposure. Developmental defects or naevoid lesions are circumcribed lesions of the skin and/or neighbouring mucosae, which are not neoplastic. objective: at this stady we studied prevalence and number of lentigo, freckle, melanocytic nevus and other Nevus in women with and without melisma. Methods and materials: in a case- control study 120 women who have melasma (case group) and 120 women who have not melasma (control group) were entered in study. They were matched for age. Subjects were examined by a dermatologist and a questioner was compeleted for every body. lesions diagnosis were done only by clinical sign and observation. collected data were analysed by soft ware of spss. Results: mean age was 29.97 ± 6.6 in case group and 29.7 ± 6.7 in control group. There were no significant difference. Prevalence of freckles was higher in control group [(24.3% versus 4.16%) P<0/001] 64.1% in case group and 16.6% of cintrol group had lentigo. there was significant difference between both group (p<0/001)mean number of lentigo in case group was 25.2 and in control group 8. (P=0.01) Prevalence of melanocytic naevus in control group was lower than case group (96.6% versus 98.3%).There was no significant difference. -

May 2015 DCCC Skin Notes Gavin R Powell, MD • Ryan J Harris, MD • Seth A Permann, PA-C • Thea N Heaton, PA-C May Special Sun spots, blotches, liver spots, melasma: hyperpigmentation, or an in- crease of brown color in the skin, has 10% off IPL many names, but what can be done about ○○○○○○○○○○○○○ this common skin issue? 10% off Obagi, HydroQ and RetAdvanz Three of the most common causes of hyperpigmentation are an accumulation of sun exposure over time, hormone effects, or injury. There are multiple options for cosmetically treating these trouble areas. Your DCCC provider is able to diagnose the problem and work with you to find the best solution. Solar lentigo (sun spot, liver spot) is the most common benign, sun-induced lesion. A solar lentigo looks like a freckle and is more often seen in fair-skinned people. They appear most commonly on the face, arms, backs of the hands, chest, and shoulders as we age. The term “lentigo maligna”, refers to a lesion that may look similar to a solar lentigo, but is actually a superficial melanoma. If you notice a freckle that looks different than the others, including having a darker & irregular color or increased texture, these could be warning signs and should be evaluated by your dermatology provider. Yearly skin checks are recommended! For the most part, lentigines are a cosmetic concern which many people are interested in having re- moved. The procedures we offer at DCCC include: Excel V laser, Intense Pulsed Light (IPL), or cryo- therapy. -The Excel V laser is an excellent option for treating solar lentigines and may be used safely in people with all skin types.
