Chronic oral breathing is characterized by respiratory and anatomic alterations found in children who breathe through their mouth only. Through open-mouth breathing, these patients develop anatomic deformities such as a typical adenoid facies. Such anatomic alterations make the lower lip of these patients more prone to UV action and its related actinic damage. This paper discusses an 11-year-ol...

Annular elastolytic giant cell granuloma is a condition characterized histologically by damaged elastic fibers associated with preponderance of giant cells along with absence of necrobiosis, lipid, mucin, and pallisading granuloma. It usually occurs on sun-damaged skin and hence the previous name actinic granuloma. A similar process occurs on the conjunctiva. Over the past three decades only fo...

Although lichen planus and vitiligo are common skin disorders, their association with two other uncommon diseases, i.e. lichen sclerosus et atrophicus and disseminated superficial actinic porokeratosis, seems to be a very rare occurrence. We report herein a 70-year-old man who developed all of these four skin disorders simultaneously.

The aim of this study was to describe the use of thalidomide in the treatment of prurigo nodularis Hyde (PNH) refractory to other treatments or in cases where other treatments cannot be used due to side effects. 77 medical records were retrospectively reviewed for the following data: sex, age, age at the beginning of thalidomide treatment, dermatological diagnosis, duration of the skin disease,...

ISSN 0001-5555 Prurigo nodularis (PN) is a chronic and intensely pruritic dermatosis characterized by lichenified and excoriated papules and nodules. Although thalidomide has shown promise in the treatment of refractory PN, its safety and efficacy for this indication has not been firmly establi...

BACKGROUND Photodynamic therapy is a form of treatment in which a photosensitizing substance is applied to tissue and activated by a light source at a specific wavelength, thus selectively destroying cells. New light sources are being evaluated for use in the treatment of actinic keratoses. OBJECTIVES To evaluate the efficacy of photodynamic therapy with delta-aminolevulinic acid using a ligh...

Actinic granuloma is an uncommon granulomatous disease, characterized by annular erythematous plaque with central clearing predominately located on sun-damaged skin. The pathogenesis is not well understood, ultraviolet radiation is recognized as precipitating factor. We report a case of a 52-year-old woman who presented with asymptomatic annular erythematous plaques on the forehead and both che...

The diagnosis of pigmented actinic keratosis can be complicated in clinical practice. The differential diagnosis with lentigo maligna melanoma can be difficult due to common clinical and dermoscopic characteristics. We present 5 cases of pigmented actinic keratosis in 4 patients. The most common dermoscopic finding was a grayish-brown granulation with a perifollicular distribution, present in a...

We present the case of a 29-year-old black female with an initial clinical and histopathologic diagnosis of actinic lichen nitidus. Three years later, she presented with scattered hyperpigmented macules with oval pink/violaceous plaques bilaterally on her forearms and on her neck, clinically consistent with actinic lichen planus. She was treated with topical steroids at each visit, with subsequ...
