Long-Term Utility of Follicular Unit Excision in Lichen Planopilaris-Correlation of Graft Survival With Histopathological and Ultrasound Biomicroscopic Parameters.

BACKGROUND: Hair transplantation in scarring alopecia is challenging and transplant surgeons are hesitant due to fear of poor graft survival apart from the risk of reactivating the disease. OBJECTIVE: Survival rate of hair follicles transplanted in cases of lichen planopilaris (LPP). To correlate histopathological and ultrasonography findings and their impact on graft survival. METHODS: In 32 patients of inactive LPP included, a 5-cm2 recipient area was tattooed. The follicular unit density of the transplanted area was 20 to 25 FU/cm2. Postoperative follow-up was conducted at 6, 12, and 24 months. The recipient area density and ultrasound biomicroscopic parameters were assessed at each follow-up visit. RESULTS: The survival of grafts was 78.62% at 12 months, and 79.96% at 24 months. Histopathology variables studied at the time of transplantation such as epidermal atrophy, fibrosis, and inflammatory infiltrate were not found to have any effect on the graft survival. Ultrasonography parameters of the involved scalp skin were found to be markedly improved on follow-up. This suggests that the overall health of the scalp improved after hair transplantation. CONCLUSION: Follicular unit excision is a ray of hope for cases of primary cicatricial alopecia such as LPP because the result is satisfying to both the patient as well as the doctor.

"Extraction Dermoscopy": Expanding the Utility of Epiluminescence Microscopy.

INTRODUCTION: Many dermatological conditions require extraction of material from the lesion followed by visualization under a microscope. However, visualization of the extracted material can be done using a dermoscope instead. We propose "extraction dermoscopy" as an addition to the already existing treasury that dermoscopy holds. METHODS: After approval from the institutional ethics committee, a cross-sectional study was carried out in a tertiary care hospital. Polarized and non-polarized versions of in vivo dermoscopy, as well as extraction dermoscopy, were performed on a total of 77 lesions, including 5 eruptive vellus hair cysts, 2 cilia incarnata externum, 10 trichostasis spinulosa, 20 keratosis pilaris, 20 molluscum contagiosum, and 20 lesions of milia. Heine Delta 20T and Dino-Lite Premier AM4113T were employed for dermoscopic examination. RESULTS: A total of 77 lesions were selected, including 5 eruptive vellus hair cysts, 2 cilia incarnata externum, 10 trichostasis spinulosa, 20 keratosis pilaris, 20 molluscum contagiosum, and 20 lesions of milia. Extraction dermoscopy of the eruptive vellus cysts revealed skin color to brownish colored cysts with a bunch of pigmented hair. Similarly, findings of all other lesions were described and recorded post-extraction. CONCLUSION: Extraction dermoscopy helps confirm the diagnosis without visualization under a microscope. Its application in recent times makes the explanation of the nature of many disorders to patients easier, and demonstration of extracted lesions may further improve doctor-patient communication.

Evaluating the efficacy of primary excision and closure for the management of lip leukoderma and introducing the surgical site morbidity score as an effective tool for assessment of postoperative morbidity.

The lips are considered of great importance for the perception of beauty and there is still a lacuna in the attempt to successfully re-pigment resistant areas of vitiligo especially the lips. No technique evolved so far ensures 100% pigmentation with a good cosmetic appearance. To study the efficacy and cosmetic outcome following primary excision and closure in the management of lip vitiligo and assessing postoperative morbidity using the created surgical site morbidity score (SSMS). Twenty-five patients with vitiligo involving the inner margin of lower lips were posted for primary excision and closure of the vitiliginous area. Patients were followed up at 7 days and every 6 months. A SSMS including pain (P), healing time (H), and presence of complications (C) as parameters for assessment of postoperative morbidity were recorded at every follow-up visit. All patients showed healthy lip mucosa within 7 days of the procedure and no recurrence was noted at 24 months of follow up. The postoperative morbidity based on the SSMS was minimal, with a mean score of P2H8C0. Primary excision and closure technique is a safe and inexpensive modality in the management of lip vitiligo with immediate results and excellent cosmetic outcomes.

Reversal of steroid-induced lipoatrophy with serial injections of isotonic saline in a child.

The problem of side-effects of injectable corticosteroids has gradually become more acute with rampant and unlimited misuse of the drug, particularly by non-dermatologists. Serial saline injections at the site of steroid-induced lipoatrophy in a child served as a safe, relatively rapid, and cost-effective solution.

Distinguishing Lipedematous Scalp, Lipedematous Alopecia, and Diffuse Alopecia Areata.

Soft, spongy or doughy consistency of the scalp resulting from thickening of the subcutaneous layer is termed as lipedematous scalp (LS). When such soft, boggy scalp is associated with hair loss, where the scalp hair is no longer than a few centimeters, it is referred as lipedematous alopecia (LA). There have been coincidental reports of androgenetic alopecia, psoriasis, mucinosis, and discoid lupus erythematosus with LS. We report a case of LS and alopecia areata whose characteristic histopathological feature showed a "swarm of bees" appearance and thickening of subcutaneous tissue. The diagnosis of alopecia areata was further confirmed by immunohistochemistry staining of the tissue showing CD3+ T-lymphocytes around the bulb. The aim of this case report is to make readers understand that LA and LS are not different diseases and one needs to rule out other causes of alopecia in order to pick up conditions which are essentially reversible and treatable.
