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

Skin Appendage Disord 2020 Jul 25;6(4):220-223. Epub 2020 Jun 25.

Department of Dermatology, LTMMC and LTMGH, Sion West, Mumbai, India.

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.

Multiple milia formation in blistering diseases.

Int J Womens Dermatol 2020 Jun 1;6(3):199-202. Epub 2020 Apr 1.

Department of Dermatology, University of New South Wales, Sydney, Australia.

Background: Milia are superficial keratinous cysts seen as pearly white, dome-shaped lesions 1-2 mm in diameter. Milia are associated with diseases that cause subepidermal blistering, such as hereditary forms of epidermolysis bullosa, epidermolysis bullosa acquisita, bullous pemphigoid, bullous lichen planus, and porphyria cutanea tarda. Multiple eruptive milia are rare and more extensive in number than primary milia. Read More

Eruptive vellus hair cysts in identical triplets with dermoscopic findings.

Cutis 2018 Nov;102(5):367-369

Department of Dermatology, University of Illinois at Chicago, USA.

Eruptive vellus hair cysts (EVHCs) are asymptomatic, follicular, flesh-colored to hyperpigmented papules that are typically located on the chest and extremities with an unclear inheritance pattern and pathogenesis. We report a case of EVHCs in 4-year-old identical triplet girls. Our aim is to present another rare case of autosomal-dominant inheritance of EVHCs and to emphasize the utility of dermoscopy as a diagnostic aid for EVHCs that may be misdiagnosed clinically.

Trichostasis Spinulosa: An Unusual Diagnosis Presenting as a Double Lower Eyelid.

Int J Trichology 2016 Jan-Mar;8(1):21-3

Department of Pathology, ESI-PGIMSR and ESIC Medical College, Kolkata, West Bengal, India.

Trichostasis spinulosa (TS) is a relatively common but underdiagnosed disorder of the pilosebaceous follicles in which there is follicular hyperkeratosis of a dilated hair follicle with retention of telogen hairs. Clinical presentation of this disorder can be confused with comedogenic acne, keratosis pilaris, eruptive vellus hair cysts, and Favre-Racouchot syndrome. A case of a nonpruritic variant of TS in a 16-year-old boy is reported because of its unusual location as well as presentation in the lower eyelid, giving an appearance of a double eyelid. Read More

Vellus Hair Cyst of the Orbit.

Ophthalmic Plast Reconstr Surg 2017 May/Jun;33(3S Suppl 1):S89-S91

*Department of Ophthalmology and Visual Sciences, John A. Moran Eye Center, and †Department of Radiology, University of Utah School of Medicine, Salt Lake City, Utah, U.S.A.

Eruptive vellus hair cysts are a developmental abnormality of vellus hair follicles that result in small cystic papules occurring most frequently on the chest and proximal extremities. Lesions of the ocular adnexa are extremely rare, and to the best of the authors knowledge, involvement of the orbit has never been reported. The authors describe a patient with an eruptive vellus hair cyst involving the orbit. Read More

Clinical, dermoscopic, and histopathologic features of body hair disorders.

J Am Acad Dermatol 2015 May 5;72(5):890-900. Epub 2015 Mar 5.

Department of Dermatology and Cutaneous Surgery, University of Miami L. Miller School of Medicine, Miami, Florida.

Dermoscopic examination of hair and scalp, also named "trichoscopy," is an essential tool in diagnosis of hair and scalp diseases. Trichoscopy is fast and noninvasive and can be used to evaluate hair disorders in all body areas. Body hair disorders are uncommon, and most publications on their dermoscopic features are limited to case reports or series. Read More

Unusual Eyelid Dermal Keratinous Cysts of Pilosebaceous Origin.

Ophthalmic Plast Reconstr Surg 2016 Mar-Apr;32(2):93-7

*David G. Cogan Ophthalmic Pathology Laboratory; and †Ophthalmic Plastic Surgery Service, Massachusetts Eye and Ear Infirmary, Harvard Medical School, Boston, Massachusetts, U.S.A.

Purpose: To describe 2 types of previously unrecognized dermal keratinous cysts of the eyelids-2 single sebaceous duct cysts derived from the glands of Zeis and 2 cases of multiple eruptive vellus hair cysts, both types associated with the pilosebaceous apparatus.

Methods: Clinical records and paraffin sections subjected to hematoxylin and eosin and acid-fast staining were critically reviewed from each case, and additional sections were immunoreacted for cytokeratins (CKs) 7, 14, and 17.

Results: Two patients had a slowly enlarging solitary sebaceous duct keratinous cyst at the eyelid margin where the glands of Zeis are located. Read More

Clinicopathological features and expression of four keratins (K10, K14, K17 and K19) in six cases of eruptive vellus hair cysts.

Clin Exp Dermatol 2014 Jun 28;39(4):496-9. Epub 2014 Apr 28.

Department of Dermatology, Affiliated Hospital of Guangdong Medical College, Zhanjiang, Guangdong, China.

Six cases of eruptive vellus hair cysts (EVHC) were evaluated for histopathology and the immunohistochemical profile of Ki-67 and four keratins (K10, K14, K17 and K19). The pathological hallmark of EVHC was the existence of vellus hair shafts within the cystic cavity, but atypical pathological changes included two or three cysts and a foreign-body granuloma in three cases. Our results demonstrate that atypical pathological changes are not uncommon in EVHC, and indicate that based on keratin expression, it is likely that EVHC is derived from the infrainfundibulum and sebaceous duct.

Eruptive vellus hair cysts.

Dermatol Online J 2012 Dec 15;18(12). Epub 2012 Dec 15.

The Ronald O. Perelman Department of Dermatology, New York University School of Medicine, USA.

Eruptive vellus hair cyst (EVHC), described initially in 1977, is a benign dermatologic condition that is characterized by the sudden appearance of monomorphic, follicular, asymptomatic, small papules in children and young adults. The diagnosis is based on the histopathologic findings of stratified-squamous epithelium with a granular layer that surrounds a cystic space filled with laminated keratin and a variable number of vellus hair cysts. EVHC can be associated with steatocystoma multiplex. Read More

Dermoscopy distinction of eruptive vellus hair cysts with molluscum contagiosum and acne lesions.

Pediatr Dermatol 2012 Nov-Dec;29(6):772-3. Epub 2012 May 29.

Pediatric Dermatology Department, Hospital Infantil of México Federico Gómez, Mexico City, Mexico.

Eruptive vellus hair cysts are benign lesions that can be difficult to distinguish from other skin conditions, including molluscum contagiosum and acne vulgaris. Diagnosis can be corroborated with histopathology. We emphasize differing dermoscopy features to help distinguish eruptive vellus hair cysts from molluscum contagiosum or acne. Read More
