Background: The Q-switched neodymium: yttrium aluminum garnet laser (QS-Nd:YAG) is effective in the treatment of tattoos and different pigmentary conditions; however, little has been published regarding the removal of facial cutaneous pigmented lesions. The aim of this study was to determine the effectiveness and safety of QS-Nd:YAG laser in the treatment of facial pigmentary lesions in Indian patients. Methods: Data of 100 patients with pigmented facial lesions treated with QS-Nd:YAG laser were analyzed. Clinical improvement of skin lesions was assessed by the physician’s global assessment of two blinded observers. This was done based on photographs taken at the baseline and after the last treatment session. Side effects were recorded if present, and patient satisfaction was evaluated after each treatment session. Results: The majority of the patients had post-inflammatory hyperpigmentation (n=41), followed by melasma (n=19), photomelanosis (n=15), nevus of Ota (n=5), periorbital melanosis (n=5), nevus spilus (n=3), Riehl melanosis (n=3), Café-au-lait macules (n=2), freckles (n=2), lichen planus pigmentosus (n=2), compound nevus (n=1), Hori’s nevus (n=1), and pigmentary demarcation lines (n=1). 10% of patients showed more than 50% improvement in pigmentation from the baseline level; no response was seen in 22% of patients, while 7% experienced worsened pigmentation. Conclusion: The degree of improvement and efficacy in clearing pigmentation is partial, variable, and inconsistent. Worsening of pigmentation may be seen and needs to be discussed with the patient prior to treatment

Phakomatosis Pigmentovascularis (PPV) is a rare cutaneous congenital malformation syndrome, defined as simultaneous occurrence of congenital cutaneous vascular and pigmentary anomalies. As most of the reported cases are from Far East countries, especially Japan, we reported a case of PPV type IIa in an Iranian patient. This case was unusual because of the coexistence of unilateral extensive port-wine stains all over the left body side and left hard palate and a right plantar port-wine stain.

A 24-year-old woman presented with asymptomatic hyperpigmented bilateral patches on her temples, eyelids and forehead since birth. Furthermore, the patient had a congenital grey patch, compatible with Mongolian spot, on her buttock. She had no vascular or other cutaneous lesion. Histopathologic examination revealed bipolar dendritic melanocytes dispersed in a ribbon-like pattern between the collagen fibers and around the neurovascular bundles of the dermis. As far as we know, this is the first case of bilateral “congenital” nevus of Ota in association with a Mongolian spot reported in a patient.
