BACKGROUND Acral lesions of vitiligo are usually resistant to conventional lines of treatment as well as surgical interventions. OBJECTIVE To clarify causes underlying resistance of acral lesions to pigmentation in vitiligo by studying some of the factors associated with mechanisms of repigmentation following photochemotherapy. METHODS The study included twenty patients with active vitiligo...

Early-stage mycosis fungoides (MF) can be treated with different regimens such as oral photo-chemotherapy (Psoralen and UVA-PUVA). There have been some studies showing the effectiveness of combination of interferon (IFN) with PUVA. In this study, we aimed to evaluate retrospectively the patients with early-stage MF treated with IFN + PUVA. Six patients with the diagnosis of early stage (Ia-IIa)...

BACKGROUND: Phototherapy using different wavelengths of the ultraviolet (UV) spectrum has been successfully used to treat a variety dermatoses. Along with positive effects this intervention, there are both acute and long-term side that should be taken into account by clinicians.
 AIM: study tolerability safety phototherapy (PUVA UVB-311 nm) in patients moderate severe psoriasis.

It has been suggested that trioxsalen bath and ultraviolet (UV) A (PUVA) is associated with a very low or no risk of non-melanoma skin cancer, but the numbers of patients in individual studies have been limited. In order to attain statistically relevant information about the cancer risk associated with trioxsalen bath PUVA, two follow-up studies were combined and the joined cancer incidence was...

Sir, The development of melanocytic lesions following treatment with psoralen and ultraviolet A (PUVA therapy) is well documented. The first case of lentigines induced by cosmetic UVA tanning was reported in the 1980s (1), and another three cases have been published since then (2 – 5). We report the case of a woman with systemic lupus erythematosus (SLE) who developed generalized persistent mel...

Immunocytochemical techniques using antibodies to the specific T6 and Ia (Major Histocompability Complex, class 11, human HLA-Dr) antigens were used to determine the densities of epidermal Langerhans cells (LC) in psoriasis patients treated with the aromatic retinoid RO 10-9359. Fourteen patients were treated with the aromatic retinoid and were skin biopsied before, during and after therapy. Tw...

Mycosis fungoides (MF), the commonest variant of primary cutaneous T cell lymphoma (CTCL), is relatively uncommon among the Asians. Hypopigmented mycosis fungoides is a rare variant usually observed in dark-skinned individuals, especially children. Hypopigmented MF usually responds well to therapy, particularly to PUVA, and has a comparatively benign course. Mycosis fungoides in a 16-year-old b...
