Abstract
Facial soft tissue lesions in children are often classified based on their structure or cellular origin and can be benign or malignant. This review focuses on common facial soft tissue lesions in children, their clinical morphology, natural history, and medical and surgical management, with an emphasis on those considerations unique to soft tissue lesions present at this anatomic site.

Abstract
Adnexal neoplasms of the eyelid encompass a wide variety of benign and malignant tumors of sebaceous, follicular, and sweat gland origin. Due to the specialized structures of the eyelid, these neoplasms present differently when compared with those of other locations. Although most dermatologists and ophthalmologists are familiar with the commonly reported adnexal tumors of the eyelid, such as hidrocystoma, pilomatrixoma, and sebaceous carcinoma, many other adnexal neoplasms have been reported at this unique anatomic site. Accurate and timely identification of these neoplasms is essential, as alterations of eyelid anatomy and function can have a negative impact on eye health, vision, and quality of life. We review the clinical and histopathologic features of common and rare eyelid adnexal neoplasms and discuss proposed treatment options.

Abstract
BACKGROUND Nevus sebaceous (NS) is a rare congenital skin lesion affecting approximately 0.3% of all newborns. Although benign, NS lesions can harbor malignant secondary tumors. The published rate of development of these malignant tumors varies. This meta-analysis aimed to identify the rate of malignant and benign secondary neoplasms occurring in NS. METHODS A literature search was conducted using PubMed, Embase, and Web of Science from inception to April 2023. Eligible studies reported incidence or risk of secondary neoplasms in patients with NS. Two independent reviewers screened studies, extracted data, and assessed the quality of included studies. The primary outcome was the pooled incidence of secondary neoplasms. Studies with sample sizes greater than 50 patients were eligible for meta-analysis using the random-effects model. RESULTS Twenty-eight studies were identified, 22 of which were eligible for meta-analysis. The overall rate of secondary neoplasms was 12.8% (95% confidence interval [Cl], 9.2%-17.6%). The rates of development of malignant and benign tumors were 2.4% (95% CI, 1.4%-4.1%) and 10.3% (95% CI, 7.5%-13.9%), respectively. The rate of development of basal cell carcinoma was 1.7% (95% CI, 0.9%-3.2%), whereas the rate of the development of syringocystadenoma papilliferum was 3.6% (95% CI, 2.5%-5.3%) and that if trichoblastoma was 2.6% (95% CI, 1.7%-3.8%). CONCLUSIONS Although the rate of development of malignant tumors within a primary NS lesion is low, it is not negligible. Prophylactic early excision remains a viable approach to prevent secondary malignant neoplasms, address cosmetic and functional complications, and preempt the need for complex reconstruction in the future. We propose that resection of NS lesions in childhood remains a reasonable first-line option in the appropriate patient keeping in mind that it may leave an undesirable scar.

Abstract
INTRODUCTION Schimmelpenning-Feurstein-Mims Syndrome (SFMS) is a rare neurocutaneous disorder. Herein, we describe a novel case and review the phenotypic spectrum and molecular findings of SFMS from an ophthalmology perspective. METHODS Clinical case including presentation, management, pathology, and genetic analysis is described. A literature search on Schimmelpenning-Feuerstein-Mims and its synonyms, Linear nevus sebaceous syndrome, Organoid nevus syndrome, Jadassohn nevus phacomatosis, and Solomon syndrome, was conducted. An updated review and description of published cases with identified genetic mutations are described. RESULTS A 13-year-old boy with SFMS presented with acute right eye pain and an enlarging orbital mass. Excisional biopsy of the mass revealed an orbital choristoma. Genetic analysis of the orbital tumor confirmed a KRAS c.35 G>A, p.G12D mutation. A literature search revealed 19 cases of SFMS with mutations in the RAS-pathway. KRAS, HRAS, and NRAS mutations were identified in 74%, 21%, and 5% of patients, respectively. Ophthalmic pathology was seen in 83% of patients. Systemic findings varied and involved the skin, central nervous system, and eyes most commonly. DISCUSSION SFMS, a rare neurocutaneous disorder, results from postzygotic mosaic mutations in the RAS/MAPK pathway. Patients present with various systemic findings and ophthalmic manifestations occur in most cases. This is the first case description of a KRAS mutation identified in an orbital choristoma in SFMS. The disease is described under various names in the literature, and we propose that all syndromic cases with mosaic RAS mutations be reported under the eponym, SFMS.

Abstract
BACKGROUND AND OBJECTIVES Tumor of follicular infundibulum (TFI) has been described as a neoplasm - isolated and multiple - and in association with other lesions. Its histopathologic definition is controversial. PATIENTS AND METHODS We present a histopathologically analyzed series of 28 patients with TFI features. This has been supplemented by a search in MEDLINE on the literature on this subject. The corresponding figures given in these articles have been discussed and analyzed. RESULTS Patients comprised 16 women and twelve men. TFI features were seen in five patients with nevus sebaceous, two trichofolliculomas, one dilated pore Winer, eight viral warts, one dermatofibroma, six seborrheic keratoses, three actinic keratoses, one invasive squamous cell carcinoma, and one basal cell carcinoma in association with a squamous cell carcinoma/actinic keratosis. After study of the literature especially of solitary cases of TFI, we interpret such cases mostly as variants of seborrheic keratoses with variable degree of infundibular, isthmic and/or sebaceous differentiation with or without regression. CONCLUSIONS We regard TFI as an epithelial growth pattern which may occur in hamartomatous, inflammatory, infectious, reactive, or neoplastic conditions, in most solitary forms likely best classified within the histopathological spectrum of seborrheic keratoses.

Abstract
ZusammenfassungHintergrund und ZieleDer Tumor des follikulären Infundibulums (TFI) wurde als Neoplasie – isoliert und multipel – und in Assoziation mit anderen epithelialen Läsionen beschrieben. Seine endgültige histopathologische Definition wird kontrovers diskutiert.Patienten und MethodikWir präsentieren eine retrospektive Serie von 28 Patienten mit TFI beziehungsweise TFI‐ähnlichen Veränderungen. Ergänzend wurde die in MEDLINE aufgeführte Literatur zum Thema TFI recherchiert und die darin publizierten Abbildungen interaktiv diskutiert und analysiert.ErgebnisseUnsere Patienten waren 16 Frauen und 12 Männer. TFI‐ähnliche Veränderungen fanden sich bei fünf Patienten mit Nävus sebaceus, zwei Trichofollikulomen, einer erweiterten Pore Winer, acht Virusakanthomen, einem Dermatofibrom, sechs seborrhoischen Keratosen, drei aktinischen Keratosen, einem invasiven Plattenepithelkarzinom und einem Basalzellkarzinom in Kombination mit Plattenepithelkarzinom/aktinischer Keratose. Nach Sichtung der Literatur, insbesondere von solitären Fällen von TFI, betrachten wir diese größtenteils als Variante von seborrhoischen Keratosen mit variablem Ausmaß von infundibulärer, isthmischer und/oder sebazärer Differenzierung mit oder ohne Regression.SchlussfolgerungenWir werten TFI insgesamt als ein epitheliales Wachstumsmuster, das bei hamartomatösen, entzündlichen inkludierend infektiösen, reaktiven oder neoplastischen Prozessen auftreten und in den meisten solitären Formen am ehesten innerhalb des histologischen Spektrums seborrhoischer Keratosen eingeordnet werden kann.

Abstract
Poroma is a benign sweat gland tumour showing morphological features recapitulating the superficial portion of the eccrine sweat coil. A subset of poromas may transform into porocarcinoma, its malignant counterpart. Poroma and porocarcinoma are characterised by recurrent gene fusions involving YAP1, a transcriptional co-activator, which is controlled by the Hippo signalling pathway. The fusion genes frequently involve MAML2 and NUTM1, which are also rearranged in other cutaneous and extracutaneous neoplasms. We aimed to review the clinical, morphological and molecular features of this category of adnexal neoplasms with a special focus upon emerging differential diagnoses, and discuss how their systematic molecular characterisation may contribute to a standardisation of diagnosis, more accurate classification and, ultimately, refinement of their prognosis and therapeutic modalities.

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
Nevus sebaceus is a hamartomatous lesion characterized by epidermal, follicular, sebaceus, and apocrine gland abnormalities. Approximately 25% of affected individuals may develop benign or malignant secondary neoplasms within the preceding nevus sebaceus. Primary cutaneous apocrine carcinoma (PCAC) is a rare malignant skin tumor affecting elderly adults in their sixth decade of life. Histologically, PCAC appears as a dermal tumor displaying apocrine differentiation with decapitation secretion and malignant features. Secondary malignancy arising from nevus sebaceus is a rare complication, especially for apocrine carcinoma. To date, approximately 200 cases of PCAC have been reported in the literature, and only a few cases have developed PCAC on the scalp. Very few cases (approximately only 12) of PCACs developing in nevus sebaceus have been reported. Here, we report an extremely rare case of the coexistence of PCAC and syringocystadenoma papilliferum arising within nevus sebaceus of the scalp.

Abstract
ABSTRACT Nevus sebaceus (NS) is a cutaneous hamartoma typically found on the head and neck, with a prevalence of 0.3% in newborns. Most NS are quiescent; however, benign and malignant lesions have been reported to arise within these nevi. Malignant transformation is not common but mainly includes basal cell carcinoma and squamous cell carcinoma. Malignant melanoma arising in NS is exceedingly rare, with only 2 previously documented cases. In this article, we report the first case of malignant melanoma arising in a NS in a 68-year-old man in the United States.

Abstract
ABSTRACT Trichoepithelioma is a benign adnexal neoplasm of follicular germinative cells, with bulbs, papillae, and sheaths of perifollicular connective tissue as signs of follicular differentiation. Accordingly, trichoepithelioma may arise in any hair-bearing location, mostly on the face. That is why trichoepithelioma cannot appear in glabrous skin, and, although the dorsum of the hands and feet are a hair-bearing area, acral location is exceptional. We report the first case of trichoepithelioma localized in the finger of a 79-year-old man. It was a brown-pink, firm, 7-mm diameter, solid papule on the dorsal aspect of his left index finger. The lesion was completely asymptomatic, and he remembered to have it for many years. We describe this case highlighting its rare anatomical location and correlate its dermoscopic features with the histopathological appearance.

Abstract
ABSTRACT Trichoblastoma (TB) is a benign biphasic follicular neoplasm with differentiation toward the germinative cells and a specific follicular mesenchyme. We subtyped 349 sporadic TB according to a classification proposed by Ackerman. Two hundred forty-six (246/349, 70.5%) neoplasms were comprised of mixed subtypes. TB composed exclusively of a single pattern was less common (103/349, 29.5%). The most common pure subtype was cribriform TB followed by small nodular TB. Twelve cases (12/349, 3.4%) had unique features and are reported herein as novel histopathologic subtypes of the neoplasm.

Abstract
BACKGROUND Trichoblastoma (TB) is an uncommon benign follicular tumour for which clinical data is limited since most reports originate from pathology studies. OBJECTIVE To describe the clinical aspects of TB. METHODS This is an ancillary study of a prospective multicentre cohort of 2710 clinically suspected basal cell carcinoma (BCC), including 935 nodular BCCs. Sixty-two cases were TB: they were analysed and compared to 935 nodular BCCs. RESULTS TB mostly occurred in females (61% vs. 43% for BCC, P<0.01) of mean age 63 years. They were located on the head and neck, mainly on the nose and forehead, in 87% of cases. The mean size was 8.1mm, 77% were<10mm (55% of BCCs, P<0.001), 8% were ulcerated (vs. 21% of BCCs, P<0.02), and 47% persisted for more than 1 year (34% of BCCs, P<0.05). Most cases had a clinical presentation similar to nodular BCC, except for 5 small, flat, white papules and 1 anfractuous plaque. LIMITATIONS Cases originated from a series of tumours clinically suspected as BCCs. DISCUSSION Some 2.6% of tumours clinically diagnosed as BCC are in fact TB. TB occurs on the head, are more frequent in women, and are smaller and of longer duration than BCC. In most cases, clinical diagnosis on clinical grounds is difficult.

Abstract
Trichoblastoma is a rare benign skin adnexal tumour, belonging to the category of trichogenic tumours. The clinical and histological findings may often be confused with basal cell carcinoma, a malignant epidermal skin tumour. We report here a case of a 70-year-old man presented with a dome-shaped, dark-pigmented nodule within a yellowish hairless plaque on the scalp. The plaque had existed since childhood. However, the central pigmented nodule began appearing three months ago and enlarging gradually. The patient had no medical history. Furthermore the physical examination revealed a translucent, verrucous, and yellowish plaque, with central and pigmented nodule measuring 0.7 × 0.5 cm. Also basal cell carcinoma and trichoblastoma's diagnosis were discussed. The patient was subsequently referred to the plastic surgery department, where he underwent a total excision. The histological examination was in favour of trichoblastoma arising from the nevus sebaceus. After 24 months of checking, no recurrence was observed. Trichoblastoma is a benign adnexal tumour. Its progression to malignant trichoblastoma (or trichoblastic carcinoma) is possible, but remains exceptional. Therefore, complete excision should be proposed to the patient at the time of diagnosis.

Abstract
Nevus sebaceus of Jadassohn, or "organoid nevus," is a common, benign hamartoma of the skin consisting of epithelial and adnexal components. Its natural history and association with neoplastic growths is well documented. The majority of concomitant neoplasms are benign-trichoblastoma and syringocystadenoma papilliferum are most frequently discovered-but malignant tumors have been described. We present the case of a 58-year-old male with a congenital nevus sebaceus of Jadassohn on his left parietal scalp that had been enlarging, changing color, and bleeding over the prior year. Clinical exam and histology disclosed the presence of a trichoblastoma and porocarcinoma arising within the nevus sebaceus. Porocarcinoma is a rare, intermediately aggressive, malignant eccrine gland tumor that is frequently metastasized at presentation. Otolaryngology performed wide local resection with sentinel lymph node biopsy. This case highlights the diversity of tumors associated with nevus sebaceus of Jadassohn, potential for malignant expansion, and necessity for close monitoring and maintaining a low threshold for biopsy in evolving lesions.

Abstract
Background Linear nevus sebaceous syndrome (LNSS) is a rare genetic disease characterized by large linear sebaceous nevus typically on the face, scalp, or neck. LNSS could be accompanied by multisystem disorders including the central nervous system. Herein, we report gene mutational profile via whole exome sequencing of both lesional and non-lesional skin samples in a LNSS patient. Case presentation A 17-year-old girl presented with multisystem abnormalities, including large skin lesions, ocular disorders, abnormal bone development and neurological symptoms. A diagnosis of LNSS was established based on clinical manifestations, histopathological and imaging findings. The skin lesions were resected and no recurrence was noted at the time of drafting this report. Whole exome sequencing of genomic DNA revealed the following 3 mutations in the lesions of the index patient: KRAS (c.35G > A, p.G12D), PRKRIR (c.A1674T, p.R558S), and RRP7A (c. C670T, p.R224W), but no mutation was found in the healthy skin and peripheral blood sample of the index patient, or in the blood samples of her parents and sibling. PCR-mediated Sanger sequencing of DNA derived from lesional skin sample of the index patient verified KRAS mutation, but not PRKRIR (c.A1674T, p.R558S) and RRP7A (c. C670T, p.R224W). None of the 3 mutations was found in Sanger sequencing in skin lesions of 60 other cases of nevus sebaceous patients. Conclusions Our findings show the relevance of KRAS mutation to LNSS, providing new clues in understanding related genetic heterogeneity which could aid genetic counselling for LNSS patients.

Abstract
Secondary neoplasms in nevus sebaceous can develop during adolescence and adulthood. Trichoblastoma and syringocystadenoma papilliferum are the most common benign neoplasms, but poroma is rarely reported. A 28-year-old female presented with an asymptomatic mass on the scalp. She has had a hairless lesion on the scalp since birth. A soft mass developed on that lesion four years prior. Physical examination revealed a localized 1 cm×2.5 cm-sized brownish, verrucous-surfaced plaque with a 1 cm×1 cm-sized pedunculated erythematous tumor on the scalp. We performed skin biopsy on both the plaque and tumor lesions. The histopathological findings demonstrated the plaque lesion consistent with nevus sebaceous and the tumor lesion consistent with eccrine poroma. Surgical mass excision was performed. The patient was eventually diagnosed with eccrine poroma arising within nevus sebaceous. To the best of our knowledge, there are only six reported cases on poroma arising within nevus sebaceous. Although rarely documented in the literature, it should be considered as a secondary neoplasm within nevus sebaceous.

Abstract
Epidermal nevus syndromes are a group of rare multiorgan disorders. Schimmelpenning syndrome is a clinical variant of epidermal nevus syndromes. This congenital syndrome is characterized by the existence of nevus sebaceous and usually accompanied by abnormalities of the eyes, skeletal, cardiovascular, and central nervous systems. A 2-year-old girl presented with large, hairless, yellowish-brown plaques on the scalp and face along with multiple brownish-black verrucose plaques and brownish-black macules on almost all parts of the body. The skin-colored verrucose tumors were also found on the lips and around the mouth. Histopathological examination of the lesion on the forehead revealed hyperkeratosis, acanthosis, and sebaceous gland hyperplasia supporting the diagnosis of nevus sebaceous, while histopathological examination of the lesions on the lips and abdomen demonstrated hyperkeratosis, acanthosis, and papillomatosis consistent with verrucous epidermal nevus. The pediatrician suspected that the patient had mental retardation; however, there were no neurological, cardiac, skeletal, nor ophthalmologic abnormalities. The lesions on the lips and around the mouth were excised, and it demonstrated a good result. To conclude, epidermal nevus syndrome (e.g., Schimmelpenning syndrome) should be considered in children born with nevus sebaceous.

Abstract
Excisions of scalp nevus sebaceous (NS) presents a unique challenge due to limited soft tissue laxity, hair-bearing skin, and convex surfaces which often leave the surgeon and patient underwhelmed with the reconstructive outcome. In this study, the authors conducted an institutional review board-approved retrospective review of patients who underwent excision of pathologically proven scalp primary NS from 2003 to 2017 at our institution to better define the reconstructive outcomes and options for treatment of pediatric scalp NS. 92 patients were included in the study, 54 males (58.7%) and 38 females (41.3%). The average age at surgery was 7.24 years (0.5-16.0; SD 4.7). Local tissue undermining/galeal scoring with primary closure (LTUGS) was used for lesions with average surface area of 3.6 cm, rotational or transposition flaps (RF/TF) for lesions averaging 4.3 cm, completed serial excision for lesions averaging 13.9 cm, and tissue expansion (TE) for lesions averaging 21 cm (P <0.001). One or more poor outcomes were experienced by 35 patients (38%), with a significant difference between the surgical groups; LTUGS 37.2% (29/78), RF/TF 60% (3/5), serial excision 100% (3/3), TE 0% (0/6) (P = 0.022). Univariant binary regression analysis within the LTUGS and RF/TF groups showed that lesion size was a significant predictor of poor outcomes (P = 0.012). All specimens in this study were negative for carcinoma. Therefore, most pediatric nevus sebaceous of the scalp can be managed by a single-phase procedure though risk of poor outcomes increase with nevus size with high rates of poor outcomes even with small lesions.

Abstract
BACKGROUND Sebaceous nevus is a congenital malformation of the skin that usually occurs on the scalp or face. Syndromic forms do rarely exist with associated cerebral and ocular malformations. The skin lesions are pale at birth and become irregular by puberty. In the adult patient, tumors (usually benign) develop from sebaceous nevus. Their surgical excision during childhood can give a better result in terms of the definitive scar. OBJECTIVES The aim of this study is to analyze our cases of syndromic sebaceous hamartoma, perform a review of the existing literature, and propose guidelines for the therapeutic plan. METHODS This is a retrospective study reviewing the cases of syndromic sebaceous nevus treated in the Department of Orthopedic Plastic Pediatric Surgery in Montpellier, France, and the Department of Pediatric Surgery in Lausanne, Switzerland, between 1994 and 2016. RESULTS The files of six patients with syndromic sebaceous nevus were analyzed. The average age at the first consultation was 4 months. The location was craniofacial in all cases. Cerebral radiological imaging was performed on all patients; two showed abnormal findings. Four patients underwent ophthalmic examination, which all revealed abnormalities. Three patients had other associated malformations. Three patients presented with epilepsy or learning difficulties in the course of follow-up. CONCLUSION All patients presenting with extensive sebaceous nevus of the craniofacial region should benefit from cerebral imagery and ophthalmic examination since there is a very high probability of associated abnormalities. The developmental problems encountered could not be definitively associated with the skin malformations.

Abstract
Knowledge of the molecular underpinnings of many epidermal nevi and epidermal nevus syndrome has expanded rapidly in recent years. In this review and update on epidermal nevus syndrome, we will cover recent genetic discoveries involving epidermal nevi, including nevus sebaceus, keratinocytic epidermal nevus, nevus comedonicus, congenital hemidysplasia with ichthyosiform nevus and limb defects syndrome, phakomatosis pigmentokeratotica, Becker's nevus, porokeratotic adnexal ostial nevus, inflammatory linear verrucous epidermal nevi, and cutaneous-skeletal hypophosphatemia syndrome. We will discuss how newly defined mutations relate to the biology reflected in the cutaneous patterns seen in these mosaic disorders and how new molecular data has informed our understanding of these diseases and shaped management decisions.

Abstract
BACKGROUND Nevus sebaceus of Jadassohn (NSJ) is a complex cutaneous hamartoma with various clinical appearances. AIM To describe different dermoscopic patterns of this nevus according to its evolutionary stages. METHODS This was an analytical study of NSJ carried out in the Department of Dermatology at the University Hospital Hassan II, Fez, Morocco. RESULTS Thirteen patients with a NSJ were enrolled in the study. Elevated verrucous plaques were noticed in 9 patients, homogeneous tumors were described in 2 NSJ, an alopecic patch was found in 1 case, and we had 1 case of malignant transformation into basal cell carcinoma. The dermoscopic aspects of NSJ described in our study were yellowish or brown globules aggregated in clusters on a yellow background. This pattern was significantly related to the first stage of an alopecic patch (p = 0.001). Whitish-yellow lobular aspect and grayish papillary appearance were significantly related to verrucous plaques (p = 0.003). Homogeneous yellow-whitish pattern was related to nodules (p = 0.005). CONCLUSION The establishment of specific dermoscopic features of NSJ according to its evolutionary stages is important for its diagnosis and especially its monitoring in order to detect malignant transformation.

Abstract
BACKGROUND Trichoblastoma is a rare benign skin tumour that must be differentiated from basal cell carcinoma for its benign course and favourable outcome. OBJECTIVES To describe clinical and dermoscopic features of solitary primitive trichoblastoma and to compare them with trichoblastic basal cell carcinoma (tBCC). METHODS Digital dermoscopic images of 19 trichoblastoma and 19 tBCC were compared and reviewed by a dermatologist experienced in dermoscopy. RESULTS The most striking dermoscopic difference between trichoblastoma and tBCC was the presence of blue-grey globules and blue-grey ovoid nests that were found to be more frequent but not exclusive of tBCC. Arborizing vessels were found both in trichoblastoma and tBCC, with a lower frequency in the latter. CONCLUSION Histology remains the gold standard to differentiate trichoblastoma from tBCC.

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
Nevus sebaceus (NS) and Becker's nevus (BN) are two variants of epidermal nevi. NS clinically presents as a yellowish-orange, hairless plaque on the scalp, face, or neck, while BN presents as a tan-to-brown hyperpigmented, sometimes hypertrichotic, plaque typically on the chest and shoulder. Histologically, NS displays mature or nearly mature sebaceus glands as well as acanthosis and fibroplasia of the papillary dermis. BN shows variable papillomatosis, acanthosis, and hyperkeratosis, with hyperpigmentation of the basal/suprabasal layer. While the genetic basis of NS is thought to be due to post-zygotic mutations in the Harvey rat sarcoma viral oncogene homolog (HRAS)/Kristen rat sarcoma viral oncogene homolog (KRAS) genes, the genetic basis of BN is relatively unknown and is implicated with paradominant inheritance. In some patients, NS and BN can each be associated with additional cutaneous and extra-cutaneous anomalies, ranging from benign or malignant tumors to multiple organ irregularities. Due to the wide range of possible associations, treatment for NS and BN is devised on a case-by-case basis. In this article, we review the features, etiology, and diagnosis/management of NS and BN, with a focus on associations. We also report a patient who concomitantly presents with both lesions.

Abstract
The term epidermal nevus syndrome (ENS) has been used to describe the association of epidermal hamartomas and extracutaneous abnormalities. Although many continue to use the term "ENS," it is now understood that this is not one disease, but rather a heterogeneous group with distinct genetic profiles defined by a common cutaneous phenotype: the presence of epidermal and adnexal hamartomas that are associated with other organ system involvement. One commonality is that epidermal nevi often follow the lines of Blaschko and it appears the more widespread the cutaneous manifestations, the greater the risk for extracutaneous manifestations. The majority of the extracutaneous manifestations involve the brain, eye, and skeletal systems. The CNS involvement is wide ranging and involves both clinical manifestations such as intellectual disability and seizures, as well as structural anomalies. Several subsets of ENS with characteristic features have been delineated including the nevus sebaceus syndrome, Proteus syndrome, CHILD syndrome, Becker's nevus syndrome, nevus comedonicus syndrome, and phakomatosis pigmentokeratotica. Advances in molecular biology have revealed that the manifestations of ENS are due to genomic mosaicism. It is likely that the varied clinical manifestations of ENS are due in great part to the functional effects of specific genetic defects. Optimal management of the patient with ENS involves an interdisciplinary approach given the potential for multisystem involvement. Of note, epidermal nevi have been associated with both benign and malignant neoplasms, and thus ongoing clinical follow-up is required.

Abstract
PURPOSE OF REVIEW Children and their parents typically present to pediatricians to discuss treatment options for melanocytic nevi, nevus sebaceus, port-wine stains, and hemangiomas. Each of these conditions may be medically managed, but in some situations surgical intervention may be preferable. RECENT FINDINGS Although recent studies have improved our understanding of melanoma risk among patients with congenital nevi, prospective trials are needed to more accurately assess whether surgical excision mitigates this risk. The risk of basal cell carcinoma within nevus sebaceus appears to be low, but more conclusive data requires further studies with modern immunohistochemical analysis. Pulsed dye laser is effective for treating port-wine stains, although the optimal timing is controversial. While oral and topical beta blockers have revolutionized the treatment of proliferating infantile hemangiomas, laser and/or surgical excision are useful in selected situations. SUMMARY Excisional and/or laser surgery are indicated for certain common dermatologic conditions in children, although the optimal timing of these interventions is often subjective. Pediatricians should be familiar with why and when to refer patients for surgery of these common dermatological conditions.

Abstract
A 53-year-old woman had had a pale-brown lesion on her right cheek and neck from birth. Since she was about 40 years old, part of the lesion had gradually elevated and increased in size. At the first examination, there was a huge mass measuring 110 x 70 x 35 mm on the right cheek. A wide local excision of the area including a superficial parotidectomy and submandibular lymph node dissection was performed, followed by full thickness skin grafting. Histological examination of the tumor revealed an invasive dermal neoplasm characterized by lobes that were composed of foamy cells stained with Sudan-IV mixed with many atypical cells showing remarkable variation in the shapes and sizes of their nuclei. The surrounding epithelial changes were consistent with nevus sebaceus. From these findings, the gigantic tumor was diagnosed as a sebaceous carcinoma arising in nevus sebaceus.

Abstract
Meningothelial hamartoma is a rare lesion of ectopic meningothelial elements that usually presents on the scalp at birth or in early childhood. The characteristic spindle cells infiltrate through collagen and stain positively for epithelial membrane antigen and vimentin but are negative for CD31 and CD34. This distinguishes meningothelial hamartoma from vascular tumors. Nevus sebaceus is a fairly common lesion that has been associated with several different benign tumors, including trichoblastoma and syringocystadenoma papilliferum. We describe the case of a 17-month-old girl who presented with a meningothelial hamartoma in association with a nevus sebaceus. To the best of our knowledge, this is the second case reported.

Abstract
Nevus sebaceus of Jadassohn is a congenital cutaneous hamartoma comprised of multiple skin structures. It has the potential to develop into variety of neoplasms of various epidermal adnexal origins. While multiple tumors may occasionally arise, it is unusual for more than four tumors to arise simultaneously within a single sebaceus nevus. Here in, we report a case of a 70-year-old woman with six neoplastic proliferations including a syringocystadenoma papilliferum, pigmented trichoblastoma, tubular apocrine adenoma, sebaceoma, tumors of follicular infundibulum and superficial epithelioma with sebaceus differentiation arising in a long standing nevus sebaceus on the scalp. Our case is extraordinary because a single nevus sebaceus contained six neoplastic proliferations with differentiation toward the folliculosebaceous-apocrine unit.

Abstract
BACKGROUND Nevus sebaceus is commonly associated with the development of secondary neoplasms. Data on the frequency of malignant tumors vary considerably in published reports. OBJECTIVE We sought to analyze the distribution of secondary neoplasm in nevus sebaceus. METHODS A retrospective analysis of all cases of nevus sebaceus diagnosed at the Ackerman Academy of Dermatopathology from 1999 to 2012 was conducted. RESULTS A total of 706 patients (707 specimens) were included in the study. Trichoblastoma was the most frequent benign tumor (n = 52, 7.4%) followed by syringocystadenoma papilliferum (n = 33, 5.2%). Malignant tumors were present in 2.5% of the specimens with basal cell carcinoma being the most common (n = 8, 1.1%) followed by squamous cell carcinoma (n = 4, 0.57%). The incidence of secondary neoplasms was statistically related to age and anatomic site (P < .05). Almost all malignant tumors were seen in adults. LIMITATION Some of our cases were referred for second opinion and there may be a bias in our data toward unusual secondary neoplasms. CONCLUSION Our study confirms that most of the secondary neoplasms arising in association with nevus sebaceus are benign. As no malignant tumors were seen in children, we believe it is reasonable to delay surgical management until adolescence.

Abstract
We report a case of a 48-year-old Malay female who presented with multiple tumors arising from a large nevus sebaceus on her right parieto-temporal scalp. Histologically, the tumors corresponded to a sebaceoma with carcinomatous change, a poroma and a trichoblastoma. Immunohistochemical staining of the sebaceous tumor with p53 showed strong within the areas of carcinomatous change, while there was negative to weak staining within the sebaceoma-like areas. A discussion on the potential secondary neoplasms from a nevus sebaceus ensues, with a review of this literature on multiple tumors from a nevus sebaceus.

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.
