Juvenile hyaline fibromatosis and infantile systemic hyalinosis are rare autosomal recessive disorders of infancy and early childhood that are histologically characterized by deposition of hyaline material. The main clinical features are papulo-nodular skin lesions, gingival hypertrophy, joint contractures, and bone abnormalities. However, infantile(More)
BACKGROUND Non-ablative methods have been attempted in treating atrophic facial scars, but the histologic findings do not always coincide with the clinical results and patient satisfaction. OBJECTIVE To study the effects and safety of the Nd:YAG laser for treating atrophic facial scars. MATERIAL AND METHODS Twelve subjects (skin phototypes II-V) with(More)
PURPOSE To study and compare the appearance of hairs from patients with Chédiak-Higashi and Griscelli-Prunieras syndromes under light and polarized light microscopy. METHOD Hairs from 2 Chédiak-Higashi and 2 Griscelli-Prunieras patients were obtained and examined under normal and polarized light microscopy. RESULTS Under light microscopy, hairs from(More)
BACKGROUND Frontal fibrosing alopecia is considered a particular clinical form of lichen planopilaris that primarily involves the scalp hair over the frontal hairline. Concomitant involvement of vellus at different body sites has recently been reported. To our knowledge, this is the first report on the involvement of facial vellus by effects of the(More)
Toxic epidermal necrolysis-like lesions have been described in the setting of lupus erythematosus, and have been considered as a specific hyperacute variant of cutaneous lupus erythematosus, with features different from classical drug-related toxic epidermal necrolysis. We report here a series of three patients with lupus erythematosus who presented with(More)
A 70-year-old Japanese female developed tiny papules on her bilateral ears 2 years previously. A histological study of a biopsy specimen revealed that amorphous materials were present in the widened dermal papillae. Because these materials were positive for both Congo red and Dylon, we diagnosed the lesion as primary cutaneous amyloidosis of the auricular(More)
Elejalde syndrome is a rare autosomal recessive condition, with only 10 reported cases through 2001. It is characterized by silvery hair, pigment abnormalities, and profound central nervous system dysfunction. The differential diagnosis includes Griscelli and Chediak-Higashi syndromes, which present with silvery hair, pigment abnormalities, central nervous(More)
BACKGROUND Melasma is a frequent and difficult to treat skin disorder. Results of laser therapy are inconsistent. OBJECTIVE To determine the safety and efficacy of low-fluence Q-switched neodymium-doped yttrium aluminum garnet (QS Nd:YAG) laser for melasma treatment and assess recurrence rates and histopathologic findings before and after treatment.

OBJECTIVE To evaluate voriconazole in the treatment of extensive cases of chromomycosis. Chromomycosis is a chronic infection, which is extremely difficult to eradicate, and is caused by dematiaceous (dark-colored) fungi which affect the skin and subcutaneous tissues, with Fonsecaea pedrosoi being the major etiologic agent. Drugs such as itraconazole,(More)
