Selective therapy (cryo or scalpel) combined with multimodal therapy for treating keloids.

Background: Keloids are less responsive to any single treatment modality; hence, there is a need for combination therapy that can yield satisfactory outcomes. Objective: The present study assessed efficacy and safety of combination therapy-surgical excision or cryotherapy and intralesional corticosteroids along with 5-fluorouracil [IL (S + 5-FU)] injection, followed by silicone gel sheet (SGS) under compression therapy in the treatment of keloids. Materials and Methods: This was a retrospective, observational study comprising 21 clinically diagnosed keloid patients. All patients were treated with the stated combination therapy. Data about demographic, lesions, procedural characteristics, and treatment outcomes were reported. Results: Of 21, 11 (52.4%) patients were treated with liquid nitrogen (LN2) cryotherapy, and 10 (47.6%) patients were treated with surgical excision. Mean age was 30.8 ± 7.6 (range: 14-44) years with slight male (52.4%) predominance. A mean surface area of keloid lesion was 96.8 ± 170.5 cm3. The most frequently involved site was auricle (8 [38.1%] patients). Patients received the following types of treatments: intralesional LN2 cryotherapy (6 [28.6%]), intralesional excisional surgery (6 [28.6%]), surface LN2 cryotherapy (5 [23.8%]), and extralesional excisional surgery (4 [19.0%]). Complications of recurrence (2 [9.5%]), secondary infections (2 [9.5%]), persistent postinflammatory hypopigmentation (1 [4.8%]), and atrophic scarring with postinflammatory hyperpigmentation (1 [4.8%]) were reported. After a study period of 2.5 years, 100% cure rate was achieved. Conclusion: Combination therapy of surgical excision or cryotherapy and IL (S + 5-FU), followed by SGS under compression, was safe and effective in treating keloids.

Efficacy and Safety of Carbon Dioxide Laser Ablation Combined with Manual Dermabrasion and Intralesional 5-Fluorouracil Injection in Bowen's Disease.

Background: Bowen's disease (BD) is a precancerous in-situ squamous cell carcinoma and has a high recurrence rate with any single treatment modality, necessitating combination therapy for a successful outcome. Aim: This study aimed to the efficacy and safety of carbon dioxide (CO2) laser ablation followed by manual dermabrasion and intralesional 5-fluorouracil (IL 5-FU) injection as combination therapy for BD. Materials and Methods: This was a retrospective, observational study comprising 29 clinically and histopathologically diagnosed BD patients with no history of prior treatment. Demographic characteristics and clinical examination of the lesions and regional lymph nodes were retrieved. All patients were subjected to CO2 laser ablation followed by manual dermabrasion and IL 5-FU injection. Results: Mean age was 61.93 ± 9.31 years with male preponderance (62.1%). Trunk (48.3%) was the most frequently involved site. Mean tumor size was 40.8 ± 16.4 mm (range: 15-86 mm). All lesions healed with a cure rate of 96.6%. Complications seen in patients included atrophic scarring with persistent post-inflammatory hyperpigmentation in three patients (10.3%), secondary infection in two cases (6.9%), and hypertrophic scar with early keloid in one patient (3.4%). Recurrence was reported in one patient (3.4%). Limitation: The study was limited by retrospective study design, small sample size, and no comparison with standard therapy. Conclusion: Combination approach using carbon dioxide laser ablation followed by manual dermabrasion and IL 5-FU injection has been proved to be effective, efficient and safe with good functional, oncological and aesthetic outcomes in treating BD.

Retrospective analysis of ultrathin skin grafting over carbon dioxide ablated lesions supplemented with excimer lamp (308 nm) therapy in stable vitiligo.

Background Of all the tissue or cellular grafting techniques used in the treatment of vitiligo, melanocyte transplant/transfer through ultrathin skin grafting (UTSG) provides rapid onset of regimentation. The regimentation process is further accelerated with a combination of psoralen and ultraviolet A radiation, or psoralen and ultraviolet A obtained by sunlight or narrowband ultraviolet light B, or excimer laser/lamp (308 nm). Aims We assessed the efficacy of carbon dioxide laser ablation followed by melanocyte transplant/transfer through ultrathin skin graft sheet/sheets and further treated by excimer lamp therapy in patients with stable vitiligo. Methods One hundred ninety-two patients with stable vitiligo were treated with UTSG following carbon dioxide laser ablation and patients were then put on excimer lamp therapy. Primary efficacy was determined in terms of grades of regimentation and colour match at the end of 1-year. Results A total of 192 stable vitiligo patients with a mean age of 32.71 ± 8.55 years were recruited. Of the total 410 lesions, 394 showed excellent regimentation indicating a success rate of 96.1% at 1-year follow-up, whereas 16 (3.9%) lesions present on fingertips and toe tips showed poor or no regimentation at 3-month and 1-year follow-up. With regards to colour match, 394 (96.1%) lesions had achieved excellent colour match, and 16 lesions (3.9%) had poor or no colour match at 1-year follow-up. Limitations This was a single-center study with a small sample size. Conclusion The effectiveness of carbon dioxide laser ablation followed by melanocyte transfer/transplant through ultra-thin skin graft sheet/sheets when combined with excimer lamp therapy provides favourable cosmetic outcomes with rapid onset of regimentation in stable vitiligo.

Use of preoperative and perioperative ex vivo dermoscopy for precise mapping of margins for standard surgical excision of primary basal cell carcinoma.

Background The utility of preoperative and perioperative dermoscopy in standard surgical excision for radical excision of primary basal cell carcinoma remain unexplored. Aims To evaluate the use of preoperative and perioperative dermoscopy for precise mapping of margins during standard surgical excision of primary basal cell carcinoma. Methods In this retrospective, observational study, 17 patients clinically diagnosed with various morphological subtypes of basal cell carcinoma were included. Data about previous history, clinical examination of lesions and regional lymph nodes and preoperative dermoscopy were retrieved. After standard surgical excision had been carried out as per mapping of lateral margins, all the excised surgical specimens were subjected to perioperative dermoscopy and later reconfirmed with histopathology. Results Seventeen patients with mean age of 60.82 ± 9.99 years and median disease duration of 14 months were analysed. Clinically, basal cell carcinomas were of pigmented superficial subtype [6 (35.3%)], followed by pigmented nodular [5 (29.4%)], nodulo-ulcerative [4 (23.5%)] and micro nodular [2 (11.8%)]. Mean extension of clinical margin after dermoscopy was 0.59 ± 0.52 mm. Mean pre-assessed depth of tumour and mean depth of tumour were 3.46 ± 0.89 mm and 3.49 ± 0.92 mm, respectively. No recurrence was reported. Frequently found pre-operative dermoscopic features were maple leaf like structures [6 (35%)], blue grey dots and globules [6 (35%)] and short fine telangiectasias [6 (35%)]. Commonly observed perioperative dermoscopic features were: (1) irregular band with brown-grey pigmentation of dots, globules, streaks and pseudopodia like extensions [3 (50%)]; (2) irregular band of pseudo granulomatous structureless vascular areas in psoriasiform pattern with diffuse white streaks in pseudopodia like manner [1 (50%)]; (3) irregular band of pseudo granulomatous structureless vascular areas in psoriasiform pattern with streaks of white pseudopodia like structureless areas [1 (50%)]. Limitation This was a single-centre study with a small sample size. Conclusion This study highlights significance of preoperative and perioperative dermoscopy for precise planning and radical excision of primary basal cell carcinoma by standard surgical excision.

Milia-like idiopathic calcinosis cutis in a child with Down syndrome.

Idiopathic calcinosis cutis refers to progressive deposition of crystals of calcium phosphate in the skin and other areas of the body, in the absence of any inciting factor. Idiopathic calcinosis cutis may sometimes take the form of small, milia-like lesions. Most commonly, such milia like lesions are seen in the setting of Down syndrome. Herein, we report a 5-year-old girl with multiple asymptomatic discrete milia-like firm papules distributed over the face and extremities. A diagnosis of milia-like idiopathic calcinosis cutis associated with Down Syndrome was provisionally made and was confirmed by histopathology and karyotyping.

Generalized acquired cutis laxa type 1: a case report and brief review of literature.

Cutis laxa, clinically characterized by loose and pendulous skin related to loss of elastic tissue, is a rare heterogeneous condition. It is classified into congenital and acquired types. We report a case of generalized acquired cutis laxa type 1 in a young man following pruritic urticarial plaques. We have done a brief review of literature.

Periumbilical perforating pseudoxanthoma elasticum.

A 50-year-old woman presented with a 2-year history of a yellowish plaque studded with red brown keratotic papules in the periumbilical region. Histopathological examination from the yellow plaque showed curled and granular elastic fibers in the mid and lower dermis. Histopathological examination from a keratotic papule showed pathological elastic fibers and dense chronic inflammatory cells around areas of perforation. Clinicopathological correlation established periumbilical perforating pseudoxanthoma elasticum as the final diagnosis.

Lichen Planus Pemphigoides Presenting Preferentially Over Preexisting Scars: A Rare Instance of Isotopic Phenomenon.

An 18-year-old girl presented with multiple itchy hyperpigmented papules and plaques, along with tense blisters over the lower limbs and buttocks for last 3 months. These papules, plaques, and bullae were mostly localized to preexisting scars. The histopathological findings from papule and bulla were consistent with lichen planus (LP) and bullous pemphigoid, respectively. Direct immunofluorescence (DIF) of perilesional skin around bulla showed linear deposition of IgG and C3. Considering clinical, histopathological and DIF findings, diagnosis of LP pemphigoides (LPP) was made. The preferential localization of LPP lesions over preexisting scars was a very interesting finding in our case an extremely rare instance of the isotopic phenomenon.
