Nevus lipomatosus cutaneous superficialis (NLCS) is an uncommon benign hamartomatous condition characterized by the presence of mature ectopic adiopocytes in the dermis. It was first reported by Hoffman and Zurhelle in 1921. Clinically they areit is classified into two forms. The classical form is characterized by groups of multiple, non-tender, soft, pedunculated, cerebriform, yellowish or skin-colored papules, nodules, or plaques. The other form of NLCS clinically manifests as a solitary dome-shaped or sessile papule. The classical NLCS is mostly reported to involve the pelvic or gluteal region. We report here a case of adult-onset classical NLCS on perianal area because of its rarity and unusual location. In addition, our patient also had some rare features of NLCS, such as recurrent in nature, presence of foul-smelling discharge, and comedo-like plugs on the lesions.

Background:Oral isotretinoin is highly effective in all forms and grades of acne, even in lower dosages (<0.5 mg/kg/day). There is a paucity of comparative data on the various low-dose regimens of oral isotretinoin in the Indian literature.Objectives:To assess and compare the efficacy and tolerability of two low-dose oral isotretinoin treatment regimens (20 mg daily and 20 mg alternate days) in moderate to severe acne vulgaris.Materials and Methods:A total of 240 patients with moderate to severe acne vulgaris were selected and randomized into two groups and treated with a fixed dose of 20 mg of isotretinoin (Group A - daily and Group B - alternate days) for 24 weeks and followed up for 12 weeks post therapy.Results:A total of 234 patients completed the study. At the end of therapy, decrease in the total acne loads up to 98.99% (Group A) and 97.69% (Group B) was achieved from the baseline (P < 0.01), excellent response was observed in 98.3% (Group A) and 93.96% (Group B) patients (P = 0.166). In the severe acne, Group A performed significantly better than Group B until the end of 36 weeks. While in the moderate acne, significant difference in the response between both groups was observed only up to 12 weeks. No serious side effect was observed.Conclusion:Both isotretinoin regimens were well tolerated and found to be an effective treatment for moderate to severe acne vulgaris. However, in moderate acne 20 mg alternate day regimen may be preferred. A 20 mg daily regimen is a better choice for severe acne in terms of response.Limitation:Small sample size and short follow-up period.

Ectopic thyroid tissue (ETT) is a rare developmental anomaly of the thyroid tissue where the thyroid gland is not located in its usual position. Dual thyroid ectopia is far rarer. This case of a 5-year-old euthyroid girl with thyroglossal cyst was planned for surgery. Presurgical ultrasonography (USG) of the neck followed by thyroid scintigraphy was performed. There was absent normal thyroid gland with single ETT in neck swelling on USG. However, thyroid scintigraphy revealed two ectopic foci of thyroid tissue; one was corresponding to neck swelling, and other was superior to it at the base of the tongue along with absent eutopic thyroid gland. The repeat neck USG could demonstrate the same. The present case emphasizes that, if the thyroid gland is not visible by USG; ETT should be evaluated with thyroid scintigraphy in case of thyroid dysgenesis.
