Abstract
This case report details a rare occurrence of a vellus hair cyst presenting as a recurrent nodular swelling on the medial aspect of the right eye in a 23-year-old male. The patient underwent surgical excision guided by imaging studies, and the subsequent two-month follow-up revealed no signs of recurrence. Imaging, including contrast-enhanced computer tomography (CECT), played a crucial role in assessing the extent of the lesion and ruling out intracranial involvement. Histopathological examination confirmed the diagnosis, revealing cystic spaces with an attenuated lining containing vellus hair and marked fibrosis. The case underscores the importance of considering uncommon entities in differential diagnoses, emphasizes the efficacy of complete cyst removal in preventing recurrence, and contributes to the evolving understanding of vellus hair cysts. Further research is warranted to enhance our knowledge of their epidemiology and optimal management strategies.

Abstract
Nevus of Ota or congenital oculodermal melanosis (ODM) is characterized by brown or blue/gray asymptomatic brown or blue/gray flat lesions of the skin, mucosae, episcleral/sclera, and uvea, which are located near the trigeminal nerve's ophthalmic and mandibular branches. The main ophthalmic complications are glaucoma and predisposition to uveal melanoma. "trichilemmal cyst" is also known as "wen" "pilar cyst" or " isthmus catagen cyst". It occurs in the scalp and mimics sebaceous cysts clinically. The swelling appears smooth in outline and is filled with cytokeratin. An unusual case of a 32-year-old male with both trichilemmal cyst and nevus of Ota, a 27-year-old female, and a 47-year-old male with nevus of Ota is discussed here.

Abstract
Background Cysts are common skin abnormalities that are mostly benign; however, sometimes malignant lesions may present clinically as cystic manifestations. Benign cutaneous cysts can be of different morphological types and their diagnosis relies on histological evaluations. The most common mode of treatment is surgical excision, which is curative. Methodology This is a retrospective cross-sectional study conducted at the Department of Histopathology, Chughtai Institute of Pathology, Lahore, Pakistan from 1st January 2020 to 31st December 2022. Non-probability consecutive sampling was done, and all the cases of benign cutaneous cysts were included. All cases were microscopically reviewed by two histopathologists, and variables like age, gender, site of the lesion, and histological diagnosis were noted. The data were analyzed using IBM SPSS Statistics for Windows, Version 29 (Released 2022; IBM Corp., Armonk, New York, United States). Results A total of 1160 recorded cases of benign cutaneous cysts were included. Overall gender distribution revealed males (n=489, 42.1%) and females (n=671, 57.8%). The age range was 3 to 91 years with a mean age of 37.56 ± 16.05 years. The three most common cysts were epidermal inclusion cysts (74.3%), trichilemmal cysts (15.1%), and dermoid cysts (6.3%). Other cysts were uncommon including hidrocystoma (1.9%), steatocystoma (0.3%), verrucous cysts (0.3%), comedones (0.6%), hybrid cysts (0.2%), milia (0.3%), and vellus hair cysts (0.2%). The most common site was back (23.5%) for epidermal inclusion cysts, scalp (74.4%) for trichilemmal cysts, and eye (33.8%) for dermoid cysts. Conclusion Benign cutaneous cysts have a broad morphological spectrum with a wide age range. Epidermal inclusion cysts, trichilemmal cysts, dermoid cysts, and hidrocystoma account for the four most common types. For each of the other cyst type, the prevalence was under 1%. Female gender predominated in epidermal inclusion cysts, trichilemmal cysts, and dermoid cysts while male gender was common in other cysts. Overall majority of the cysts presented in the head and neck area.

Abstract
Steatocystoma multiplex is a disorder of the pilosebaceous unit characterized by multiple sebum-containing dermal cysts. We report the case of a 64-year-old male presented with multiple skin-colored, partially hyperemic cystic located in the scrotum area. They were accompanied by an active inflammatory process in the form of pain, swelling, hyperemia. The lesion was present for about 1 month. Previously, this patient had diagnosed with multiple steatocystoma located in the hip area and received surgical treatment.At present, such reports in the scientific databases are presented sporadically, therefore we report on multiple steatocystoma of the scrotal localization due to its rarity.

Abstract
Steatocystoma is a rare, benign cyst that mostly originates from a dermal sebaceous gland. It can be divided into steatocystoma multiplex—with multiple locations—and steatocystoma simplex occurring at a single site. The lesion is mostly located on the skin but can be found on other locations as well. This is the first case report of steatocystoma simplex that was found in the palate of a 37-year-old male. After resection with small safety margins and local wound dressing, no recurrence was detected during a follow-up of 1.5 years.

Abstract
Steatocystoma multiplex (SM) is an autosomal dominant disorder developing in adolescence or early adult age. The occurrence of multiple asymptomatic cutaneous cysts on the axillae, groin, trunk, and limbs characterizes the disease. SM is associated with a missense mutation in the keratin 17 gene (KRT17), a gene encoding for a type I intermediate filament (keratin 17 [K17]), mainly expressed in the epithelial appendages (hair follicles and sebaceous glands). Here, we report a case of appearance of multiple steatocystomas in a psoriatic patient during ustekinumab treatment, an interleukin (IL)-12/IL-23 inhibitor. Our hypothesis is that ustekinumab could have unmasked a potential genetic predisposition to SM by reducing the expression of interferon-γ and IL-17/IL-22 and consequently acting on the K17 pathway.

Abstract
Steatocystoma multiplex (SM) is a rare hamartomatous malformation of the pilosebaceous duct junction. Most cases of SM are sporadic, although less common autosomal dominant inherited forms have been reported. Steatocystoma multiplex suppurativa (SMS) is a much rarer inflammatory variant of SM, associated with severe inflammatory lesions resembling those of hidradenitis suppurativa. We describe herein a 28-year-old male with SMS who presented with extensive giant cysts on his neck, face, and scalp.

Abstract
OBJECTIVE To provide family physicians with the information needed to recognize, diagnose, and discuss available treatment options for steatocystoma multiplex (SM). SOURCES OF INFORMATION A comprehensive PubMed search using steatocystoma multiplex as either a text word or a MeSH term was conducted, and articles reporting on treatment outcomes were included. MAIN MESSAGE Steatocystoma multiplex is a benign disorder often characterized by numerous asymptomatic dermal cysts on the trunk, arms, axillae, face, thighs, and scalp. Psychological distress due to these undesirable lesions is not uncommon for this condition. A literature review identified the following SM treatments, all of which were associated with limitations: carbon dioxide laser, modified surgical techniques, cryotherapy, and medical management. Steatocystoma multiplex is challenging to treat and, at this time, effective management is most often achieved through patient education. CONCLUSION Family physicians play a critical role in the early diagnosis and management of SM. Education about treatment options and managing patient expectations might greatly alleviate the psychosocial implications of this disease.

Abstract
Objectif Renseigner les médecins de famille pour les rendre aptes à reconnaître et à diagnostiquer les stéatocystomes multiples, et à discuter des options thérapeutiques. Sources d’information Une recherche exhaustive sur PubMed a été réalisée à l’aide des titres MeSH ou des mots clés anglais steatocystoma multiplex, et les articles ayant rapporté les résultats du traitement ont été inclus. Message principal Les stéatocystomes multiples sont un trouble bénin souvent caractérisé par de nombreux kystes dermiques asymptomatiques sur le tronc, les bras, les aisselles, le visage, les cuisses et le cuir chevelu. La détresse psychologique causée par ces lésions indésirables est fréquente. Une revue des publications a relevé les traitements suivants, tous assortis de limites : laser au gaz carbonique, techniques chirurgicales modifiées, cryothérapie et prise en charge médicale. Les stéatocystomes multiples sont difficiles à traiter et, pour l’heure, la prise en charge efficace passe le plus souvent par l’éducation du patient. Conclusion Les médecins de famille sont au centre du diagnostic et de la prise en charge précoces des stéatocystomes multiples. L’éducation relative aux options thérapeutiques et à la gestion des attentes du patient pourrait grandement alléger le fardeau psychosocial de la maladie.

Abstract
Background Steatocystoma multiplex is a benign skin disorder originating from the sebaceous and nevoid ducts. Commonly classified under hamartomas, they are distributed over the trunk, neck, axillae, and groin. Methods A 28-year-old male patient complained of multiple, asymptomatic skin-colored nodules over the face of 10-year duration. Clinical examination confirmed the historic findings of nontender, polysized, flesh-colored papules and nodules over the said distribution. Results On histopathology, a cyst was noted in the mid-dermis, lined by stratified squamous, agranular epithelium, which contained degenerated keratin. Nonpolarized dermoscopy showed a structureless, cream-colored area, and polarized dermoscopy revealed a distinctive, well-circumscribed, yellowish hue which was superimposed over the facial pseudoreticular pigmentary pattern. The findings were compatible with steatocystoma multiplex, and the patient was taken up for radiofrequency ablation. Conclusion Herein, we report a rare variant of steatocystoma multiplex limited to the face and scalp subjected to dermatoscopy and characteristic histological correlation. To the best of our knowledge and following a literature search, dermoscopic features of this condition have not been reported thus far.

Abstract
Pachyonychia Congenita (PC) refers to a group of autosomal dominant disorders with variable clinical presentations. While nail dystrophy and plantar keratoderma are the most consistent features in all the variants, a myriad of other manifestations has been observed. This report highlights a case of young female presenting with multiple asymptomatic cutaneous cysts associated with plantar kearatoderma and nail dystrophy. Similar nail changes were evident in her son also. Such clinical presentation, in corroboration with histopathological evaluation of the cutaneous cyst prompted us to make a diagnosis of Pachyonychia Congenita type II.

Abstract
Background. Steatocystoma multiplex (SM) and eruptive vellus hair cysts (EVHC) are uncommon benign tumors of the pilosebaceous unit. Both SM and EVHC are characterized by smooth, asymptomatic papules or nodules, most commonly presenting on the chest, limbs, and abdomen. Most cases of SM and EVHC are sporadic, although less common autosomal dominant inherited forms have been reported. Main Observation. In this report we present two cases of cutaneous cysts exhibiting characteristics of either SM or EVHC. Both patients presented with numerous 1-2 mm asymptomatic papules and responded well to surgical expression by incision and drainage (I&D). Conclusion. SM and EVHC are similar in clinical presentation and management. Previously reported “hybrid-type” tumors present strong evidence for a relationship between the two lesions pathologically. Due to potential similarity of EVHC and SM cyst contents, I&D and subsequent microscopic examination cannot definitely differentiate between EVHC, SM, and hybrid cysts.

Abstract
Steatocystoma multiplex is a rare genetic disorder characterized by the presence of hamartomatous malformations at the junction of the pilosebaceous duct. It consists of encapsulated cystic lesions in the dermis, with adjacent sebaceous gland. When associated with inflammation, resembling hidradenitis, it is called steatocystoma multiplex suppurativa, a condition rarely reported. This is the first case of steatocystoma multiplex suppurativa reported in the Brazilian literature. Female patient, 23 years old, with papular and nodular cystic lesions that started in the armpits and groin, later spreading to the trunk, lower limbs, anticubital fossa, face and scalp. The presence of papular-nodular lesions associated with disseminated hidradenitis-like lesions in flexural areas and the histopathological diagnosis of steatocystoma defined the diagnosis of steatocystoma multiplex suppurativa.

Abstract
Steatocystoma multiplex is a well-recognized condition in which subjects develop dermal cysts generally inherited in an autosomal dominant fashion, though these can occur sporadically. This case report describes the successful treatment of a 51-year-old woman with steatocystomata limited to the face, who after two treatments with a fractionated ablative carbon dioxide laser remained free of cysts for three years. We conclude that this treatment should be considered as an efficient and effective treatment option for patients with steatocystoma multiplex.

Abstract
Steatocystoma multiplex (SM) is an uncommon disorder, characterized by numerous skin-colored subcutaneous cysts. A number of SM pedigrees have been identified with mutations in the keratin 17 (KRT17) gene. The present study examined a four-generation Chinese pedigree with an autosomal dominant mode of inheritance and examined its genetic basis. A review of the literature on KRT17 gene mutations in the SM pedigree was also performed to investigate the KRT17 gene mutation and genotype-phenotype correlation. Exon 1 of the KRTl7 gene was amplified using polymerase chain reaction (PCR) from genomic DNA obtained, which was obtained from 25 family members in the selected Chinese pedigree and from 100 unrelated control individuals. The DNA was then subjected to automatic DNA sequencing. Genealogical investigations demonstrated an autosomal dominant pattern, and direct sequencing of the PCR product revealed a heterozygous mutation, c.280C/T (R94C), which was located in exon 1 of the KRT17 gene in all 10 affected family members. The mutation was not identified in the 15 unaffected family members or in the 100 unrelated control individuals. Therefore, the present study identified a causative mutation in the KRT17 gene in a large Chinese SM pedigree, exhibiting autosomal dominance. A review of the literature suggested that, in addition to the mutation factor, other modifying factors contribute to the phenotype of familial SM.
