Two cases of tuberculoid leprosy who developed erythema multiforme bullosum (EMB) due to Dapsone (DDS) is reported. Burning and itching sensations were found to be the prominent prodromal symptoms. The patients gave history of urticaria and bronchial asthma. Salient clinical features and further management of the cases by desensitization with slow induction to DDS under cover of steroids and antihistamines have been discussed.

According to Hansen's contact rule, the digestive system should be considered as the main shock organ, yet in food allergy, this is not the case. Very often specific food triggers clinical manifestations not involving the digestive system; that is, reactions are manifested either in the respiratory system, as asthma or rhinitis, or in the skin. In these cases the BALT (broncho-alveolar lymphoid tissue) and GALT (gastrointestinal lymphoid tissue) units play a basic role in the sensitizations. The purpose of this study was to determine the most frequent skin manifestations of food allergy among children, and the most frequently involved foods. We also thought it interesting to evaluate the diagnostic reliability of the different standard immunological parameters utilized by the study team in food allergy. All patients underwent intracutaneous tests with 12 groups of the most frequent food allergens, as well as serum IgE, antigen-specific IgE against foods, and antigen-specific histamine release tests. Antigen-specific IgG4 determination was performed in some cases. The results obtained confirmed previous studies, the most common manifestations being: angioedema (48%), followed by urticaria (31%) and atopic dermatitis (21%). Regarding the frequency of sensitization to different food allergens, in mono- or polisensitization, fish and egg stand out in our environment. Certain food allergens are more frequently responsible for specific skin manifestations. Thus, for fish sensitization, the most frequent skin manifestation is atopic dermatitis (50%); for egg sensitization, angioedema is the most frequent skin manifestation (50%); and for milk, urticaria (50%). Finally, and in agreement with previous works regarding the diagnostic reliability of in vitro techniques, we found that the histamine release test offered the highest percentage of diagnostic reliability. Only for sensitization to milk proteins did antigen-specific IgE demonstrate higher reliability. Once again, we stress that our main problem is the lower reliability of skin tests against food allergens than against inhalant allergens. We emphasize the importance of food as a major factor in the etiopathogenesis of atopic dermatitis, as well as the need to complement the study, when possible, by means of the in vitro techniques described.

Although most annular lesions will be typical of a dermatophytosis, physicians must consider other possible diagnoses. Tinea corporis can often be diagnosed on the basis of a positive potassium hydroxide examination. Topical and systemic antifungals are usually curative. Pityriasis rosea is characterized by small, fawn-colored lesions distributed along skin cleavage lines. Treatment is symptomatic. Granuloma annulare is characterized by nonscaly, annular plaques with indurated borders, typically on the extremities. One half of cases resolve spontaneously within two years. Sarcoidosis can present as annular, indurated plaques similar in appearance to the lesions of granuloma annulare. Diagnosis is based on histopathology and the involvement of other organ systems. Hansen's disease can mimic tinea corporis by presenting as one or more annular, sometimes scaly, plaques. Urticaria may affect 10 to 20 percent of the population. The annular plaques lack scale and are evanescent. Subacute cutaneous lupus erythematosus can present in an annular form on sun-exposed surfaces or in a papulosquamous form. Erythema annulare centrifugum typically presents as annular patches with trailing scale inside erythematous borders.

Histopatholgoical analysis of cutaneous lesions in 195 patients with HIV/AIDS was carried out between 1989 to 1997 at tertiary level public hospital in Mumbai. 104/195 (53%) cases showed infectious diseases which comprised of molluscum contagiosum (28), condyloma accuminata (18), verruca vulgaris (7), varicella zoster (5), syphilis (14), tuberculosis (13), donovanosis (4), leprosy (2), chancroid (2), bacillary angiomatosis (2), lymphogranuloma venercum (1), Norwegian scabies (3), leishmaniasis (2), demodicidosis (1), crytococcosis (1), tinea versicolor (1). In 12 (6%) cases neoplasms were observed which included squamous cell carcinoma (9), basal cell carcinoma (2) and kaposi's sarcoma (1) case. The miscellaneous conditions were observed in 66(33.5%) cases which comprised of psoriasis (21), papular urticaria (13), Reiter's disease (7) and eosinophilic folliculitis (6). The prevalence of cutaneous tuberculosis observed in this study is high as compared with western literature while the prevalence of kaposis's sarcoma is quite low as compared with reports from Africa, USA and United Kingdom.

A 40-year male lepromatous leprosy patient presented with four, slightly erythematous patches, with multiple urticaria-like wheals, distributed over the body symmetrically and with thickened right ulnar and right common peroneal nerves. He was previously diagnosed as a case of chronic idiopathic urticaria. Slit skin smear from the patches and urticarial wheals showed a BI of 3+ and skin biopsy showed some features of borderline lepromatous leprosy (BL).

Classical acupuncture focuses primarily on treating the person, and secondarily treating the illness. The "symptoms" are regarded as "branch" expressions of a "root" (constitutional) imbalance. Different root imbalances can produce the same symptoms. Five patients with eczema, for example, may reveal five distinct root imbalances and would all be treated very differently. Because acupuncture treats the whole person, it has something to offer almost every condition. In many cases, acupuncture aims to bring about a complete cure; in others, it aims to manage the problem. Acupuncture remains a substantial part of the traditional Chinese medicine, which is used to treat many conditions including acne, alopecia, dermatitis, pruritus, psoriasis, rosacea, systemic lupus erythematosus, urticaria, herpes zoster, chicken pox, impetigo, leprosy, vitiligo, and tinea. This review introduces the historical context of acupuncture within Chinese medicine and how it relates to skin disease. Specifically, a key question is, what can we learn from the ancients with regard to their use of acupuncture as part of a holistic system of medicine, and how does this relate to the practice of modern dermatology?

Enoxaparin is a low-molecular-weight heparin that has been used widely to prevent and treat thromboembolic disorders for at least 30 years. The most common adverse skin reactions to enoxaparin are ecchymosis and skin necrosis due to vasculitis, urticaria, angioedema and erythema. Side effects from heparin administration are rare and usually located at the injection site. However, recent reports have suggested that they can also occur at a distance from the site of injection. Moreover, the etiopathogenesis has not been fully explained. In this article, we present a case of hemorrhagic bullous dermatosis associated with enoxaparin for the treatment of ischemic heart disease that developed in a patient with a past history of lepromatous leprosy.

Epidemiology of diseases is influenced by population socio-demographic circumstances. Therefore it can be modified along the time. There are no studies exploring epidemiological transition in dermatology. This study investigated the incidence of dermatoses in new patients from a Brazilian country town public service in 2003 and 2014. There was a significant increase in the incidence of sexually transmitted diseases, leprosy, melasma, pruritus and hidradenitis suppurativa. However, a prominent reduction in scheduling of appointments for surgeries of benign lesions, drug reactions, urticaria and superficial mycoses was detected. The identification of epidemiological trends guides the dimensioning of health system and professional qualification policies.

There is little data in the literature concerning dermatologic admissions. Several diseases are seasonal in incidence and clinical worsening. We performed a survey of hospitalizations in the dermatology ward of a public hospital (April/2007 to May/2017). There were 1790 hospitalizations, whose main diagnoses were infectious dermatoses, neoplasias, psoriasis, bullous diseases and cutaneous ulcers. In winter, there were fewer hospitalizations for bacterial infections and urticaria, but more for leprosy. In summer, there were fewer hospitalizations for systemic and subcutaneous mycoses, but more for zoodermatoses and erythema multiforme. In the fall, more patients were admitted with mycoses. Spring favored urticaria and angioedema, but less cases of erythema multiforme and diabetic foot.

Annular lesions can present in a variety of diseases. Knowledge of the physical appearance and history of presentation of these skin findings can help in the diagnosis. A pruritic, annular, erythematous patch that grows centrifugally should prompt evaluation for tinea corporis. Tinea corporis may be diagnosed through potassium hydroxide examination of scrapings. Recognizing erythema migrans is important in making the diagnosis of Lyme disease so that antibiotics can be initiated promptly. Plaque psoriasis generally presents with sharply demarcated, erythematous silver plaques. Erythema multiforme, which is due to a hypersensitivity reaction, presents with annular, raised lesions with central clearing. Lichen planus characteristically appears as planar, purple, polygonal, pruritic papules and plaques. Nummular eczema presents as a rash composed of coin-shaped papulovesicular erythematous lesions. Treatment is aimed at reducing skin dryness. Pityriasis rosea presents with multiple erythematous lesions with raised, scaly borders, and is generally self-limited. Urticaria results from the release of histamines and appears as well-circumscribed, erythematous lesions with raised borders and blanched centers. Annular lesions occur less commonly in persons with fixed drug eruptions, leprosy, immunoglobulin A vasculitis, secondary syphilis, sarcoidosis, subacute cutaneous lupus erythematosus, and granuloma annulare.
