Abstract
Nevus sebaceous (NS) presents as alopecia and yellowish discoloration during infantile stage. In adult stage, lesions become verrucous. Importantly, various appendageal tumors such as trichoblastoma, syringocystadenoma papilliferum and basal cell carcinoma develop during this stage. Hence it is very important to follow the course of NS for early detection of neoplasms. We are presenting a case of a 10-year-old patient with a dome-shaped, dark-pigmented nodule on the left side of neck nape, which later diagnosed as NS and removed with a carbon dioxide laser.

Abstract
BACKGROUND Membranous aplasia cutis congenita (MACC) presents at birth characterized by oval epidermis defect. Skin lesions with MACC have various clinic manifestations. In recent years, the usefulness of trichoscopy (scalp dermoscopy) has been reported for hair loss diseases. However, the dermoscopic features of MACC were mostly reported by case reports. OBJECTIVES To summarized the obvious dermoscopic characteristics of MACC. MATERIALS & METHODS These 56 cases met the clinical diagnostic criteria for MACC without forceps delivery complications or other birth injuries. To find the dermoscopic characteristics of MACC by summarizing 56 infants' dermoscopic pictures. RESULTS The dermoscopic manifestation of MACC are characterized by hair follicle openings and hair deficiency in the center of skin lesions, translucent epidermis, hair root and hair bulb arranged along the margins of skin lesion. CONCLUSION The typical dermoscopic characteristics of MACC could help clinicians to early diagnose and differential diagnosis.

Abstract
Nevus sebaceous (NS) is a common congenital hamartoma of the skin composed predominantly of sebaceous glands. Although most NS are benign skin tumors, malignant transformations have been reported. There is still controversy about the lifetime risk of malignant degeneration and precise surgical criteria. This study reports cases of malignant degeneration and suggests a surgical treatment algorithm. The medical records of patients with basal-cell carcinoma (BCC) arising from NS between January 2001 and January 2021 were retrospectively reviewed. Patient demographics including lesion location, and tumor size were investigated. The symptoms, histological findings before and after excision, complications, and recurrence during 2-year follow-up periods were investigated. Ten patients were identified with BCC arising from NS lesions. All patients were female and the mean age was 52.11 years. All patients complained of sudden morphological changes, the most common type being rapid color changes. Two cases had histological findings that showed a miss-match between punch biopsy and excisional biopsy results. No recurrence was detected 2 years after surgeries in any patients. Cases after third stage, especially in over 40 years who report morphologic changes, should undergo total surgical excision as the first approach, with strong suspicion of malignant degeneration.

Abstract
Background/aim Verrucous epidermal nevi are cutaneous hamartomas with many clinical variants. Dermoscopic features of verrucous epidermal nevus have rarely been investigated. We aimed to identify dermoscopic findings of the entity which will facilitate the diagnostic process by reducing the use of invasive diagnostic methods. Materials and methods The study included the patients with histopathologically approved verrucous epidermal nevus. Clinical, dermoscopic, and histopathological features of the patients were retrospectively reviewed and the findings identified were recorded. Dermoscopic examination was performed with a polarized-light handheld dermoscope with 10-fold magnification. Results The most common dermoscopic features were thick brown circles, thick brown branched lines, and terminal hairs. The most common vessel pattern was dotted vessels. Branched thick brown lines, brown globules, brown dots forming lines, serpiginous brown dots, white and brown exophytic papillary structures, fine scale, thick adherent scale, and cerebriform structures were the other findings. Conclusion We observed many vascular and nonvascular dermoscopic findings which were not described previously for the entity. Dermoscopic examination of the verrucous epidermal nevi may lead to more reliable clinical interpretation and thus may reduce the need for histopathological investigation.

Abstract
Cutaneous adnexal tumors include lesions with apocrine, eccrine, follicular, sebaceous, and mixed differentiation. Most are benign and sporadic, although malignant forms are occasionally observed and some cases develop in the setting of inherited syndromes. These tumors often cause immense diagnostic difficulty. Dermoscopy is a noninvasive technique that has greatly improved the diagnostic accuracy of different skin lesions, including these tumors. We provide a review of the literature on the dermoscopic structures and patterns associated with adnexal tumors. Most patterns associated with this kind of tumor are nonspecific and are observed in other nonadnexal tumors, especially in basal cell carcinomas.

Abstract
Aplasia cutis congenita (ACC) is a rare disease characterized by congenital absence of skin, affecting preferentially the scalp. Diagnosis is made clinically; however, recent studies have shown that dermoscopy can be a useful tool for the diagnosis and differentiation from sebaceous nevus. The clinical findings include a shiny atrophic alopecic patch associated with dermoscopic findings of absent follicular openings, thicker vessels and a distinct collar hypertrichosis. We report 2 cases of alopecia presenting from birth. At dermoscopy, the absence of follicular openings and the increase in the caliber of vessels led us to establish the diagnosis of ACC.

Abstract
A 4-day-old boy was referred for evaluation of an oval patch of occipital alopecia associated with caput succedaneum and ipsilateral eyelid ecchymoses. Based on the history of a prolonged, difficult labor with vacuum-assisted delivery, the diagnosis of neonatal alopecia associated with birth trauma was made. Trichoscopy showed purple dots corresponding to blood extravasation and follicular ostia. We also review the trichoscopic differential diagnosis of focal neonatal alopecia.

Abstract
PURPOSE To establish whether trichoscopy can be useful in the differential diagnosis of patchy alopecia in children. PROCEDURES The study was a retrospective analysis (2012-2015) and included 68 patients under 6 years of age. The inclusion criteria were age and the presence of 1-3 alopecia patches. A total of 124 alopecia patches were examined with the use of a videodermoscope: 102 alopecia areata, 8 tinea capitis, 6 trichotillomania, 3 temporal triangular alopecia and 5 aplasia cutis congenita. RESULTS In all aplasia cutis congenita lesions, trichoscopy revealed elongated hair bulbs visible through the semitranslucent epidermis, seen at the hair-bearing margin and radially arranged. Hair regrowth [upright regrowing hairs (44%), circular hairs (23%) and vellus hairs (20%)] was observed in the majority of alopecia areata patches. For triangular alopecia, upright regrowing hairs (100%; 3/3), vellus hairs (100%; 3/3) and circle hairs (33%; 1/3) were seen inside the alopecia patch. CONCLUSION Trichoscopy is a useful technique for the differential diagnosis of patchy alopecia in children. A novel finding in this study indicates that radially arranged hair bulbs visible through the translucent epidermis are characteristic of nonbullous type aplasia cutis congenita.

Abstract
Introduction: Nevus sebaceous (NS) presents as alopecia and yellowish discoloration during infantile stage. In adult stage, lesions become verrucous. Importantly, various appendageal tumors such as trichoblastoma, syringocystadenoma papilliferum and basal cell carcinoma develop during this stage. Hence it is very important to follow the course of NS for early detection of neoplasms. Trichoscopy, being in vivo diagnostic technique, can be utilized in this condition. as it demonstrates specific trichoscopic patterns. Patterns of NS on trichoscopy are evaluated. Materials and Methods: Study was conducted in SN Medical College, Bagalkot. It is a case series study. Ten patients with NS were studied using polarised dermoscopy. All NS lesions were subjected to histopathology for confirmation of diagnosis. Correlation of histopathological changes and trichoscopic patterns was done. Data were tabulated in Microsoft excel sheet. The results are presented in proportions and percentages. Results: Total of 10 patients including 6males and 4 females were present in the study. The mean age was 20years. Two patients were with childhood stage and 8 patients were with adulthood stage of NS. Trichoscopy showed ‘cobble stone pattern’ in 20% and ‘cerebriform pattern’ in 80% of patients. Histopathological features showed numerous and hyperplastic sebaceous glands with primordial hair follicles which were consistent with NS in all the patients. Conclusion: Trichoscopy helps in the diagnosis of NS with specific patterns. Yellowish globules in the cobblestone pattern and cerebriform patterns are specific to childhood and adult stages of NS respectively. Hence, trichoscopy is good, non-invasive diagnostic technique in NS. Authors strongly recommend regular trichoscopic examination of NS.

Abstract
BACKGROUND The epidermal nevus is a hamartomatous proliferation of the epithelium that can involve keratinocytes, sebaceous glands, the pilosebaceous unit, and eccrine or apocrine glands. It occurs in one in 1000 live births and most commonly presents as the verrucous type. Dermoscopy is a non-invasive technique commonly used to differentiate between melanocytic and non-melanocytic lesions. OBJECTIVES This study was performed to analyze dermoscopic aspects of verrucous epidermal nevi, which have not previously been described. METHODS Dermoscopic analyses of eight different verrucous epidermal nevi were conducted. Each lesion was excised, and its diagnosis was histopathologically confirmed. RESULTS In non-melanocytic lesions, a new dermoscopic feature of large brown circles was observed. This characteristic is useful in the diagnosis of verrucous epidermal nevi. CONCLUSIONS Large brown circles represent a specific dermoscopic feature for the diagnosis of verrucous epidermal nevus.

Abstract
Hair and scalp disorders in children may originate from the hair itself, scalp skin, or infectious causes and be congenital or acquired. The most common sign is alopecia, frequently brought on by tinea capitis, patchy alopecia areata, or trichotillomania. Sometimes less frequent and clinically more elusive conditions such as initial androgenetic alopecia, congenital triangular alopecia, or alopecia areata incognita may be responsible for hair loss. The noninvasive technique known as trichoscopy is being used more frequently, aiding in the prompt differential diagnosis and follow-up of many of these diseases, oftentimes providing further examination before a treatment decision is made. This review of trichoscopy of the main scalp and hair disorders afflicting children and adolescents discusses the most important dermoscopic criteria and the usefulness of this technique.

Dermoscopy on nevus comedonicus: a case report and review of the literature. Postepy Dermatol Alergol 2013; 30:252-4. [PMID: 24278083 PMCID: PMC3834704 DOI: 10.5114/pdia.2013.37036] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2012] [Revised: 02/15/2013] [Accepted: 06/23/2013] [Indexed: 11/17/2022] Open
Abstract
Nevus comedonicus (NC) is a very rare, benign hamartoma characterised by the occurrence of dilated, comedo-like openings, typically on the face, neck, upper arms, chest or abdomen. In uncertain cases, histopathological examination confirms the diagnosis. The authors suggest dermoscopy as a rapid and useful method of initial diagnosis of nevus comedonicus based upon its distinctive dermoscopic features. The dermoscopy reveals numerous light- and dark-brown, circular or barrel-shaped, homogenous areas with prominent keratin plugs.

Abstract
The nevus sebaceous of Jadassohn usually affects the face or scalp. It tends to evolve in three stages, and the final stage is characterized by the appearance of tumours. We present the case of a facial nevus sebaceous of Jadasshon in which a basal cell carcinoma developed. We also explore the diagnosis of this disease, which was established through dermoscopy, and propose using this technique in the clinical follow-up of this type of hamartoma, thereby allowing the early detection of cancer development.

Abstract
Epidermal nevus syndrome (ENS) is an inclusive term for a heterogeneous group of congenital disorders characterized by the presence of epidermal nevi associated with systemic involvement. These disorders, as are all primary neurocutaneous syndromes, are neurocristopathies. The epidermal nevi that follow the lines of Blaschko and most systemic anomalies in skeletal, ocular, cardiovascular, endocrine, and orodental tissues, as well as lipomas, are due to defective neural crest. The most important and frequent anomaly in the brain in all forms of epidermal nevus syndromes (ENSs) is hemimegalencephaly (HME). This malformation often is not recognized, despite being the principal cause of neurological manifestations in ENSs. They consist mainly of epilepsy and developmental delay or intellectual disability. The onset of epilepsy in ENS usually is in early infancy, often as infantile spasms. Several syndromic forms have been delineated. I propose the term "Heide's syndrome" for those distinctive cases with the typical triad of hemifacial epidermal nevus, ipsilateral facial lipoma, and hemimegalencephaly. Most ENSs are sporadic. The mechanism is thought to be genetic mosaicism with a lethal autosomal dominant gene. Specific genetic mutations (PTEN, FGFR3, PIK3CA, and AKT1) have been documented in some patients. The large number of contributors for over more than a century and a half to the description of these disorders precludes the use of new author eponyms.
