    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.
    Ophthal 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.
    Ophthal 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

    Eruptive vellus hair cysts: a systematic review.
    Am J Clin Dermatol 2012 Feb;13(1):19-28
    Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, FL,
    We report the results of the first systematic review of the worldwide literature on eruptive vellus hair cysts (EVHC). It is likely that EVHC are less rare than it may appear from the scarcity of related publications in the literature. EVHC may be present at birth and may appear at any age, although they show a clear trend towards occurring during the first 3 decades of life. Read More

    Comparative treatment of multiple vellus hair cysts with the 2940 nm Er:YAG and 1540 nm Er:Glass laser.
    J Cosmet Laser Ther 2011 Oct;13(5):223-6
    Department of Dermatology, Venerology and Allergology, University of Leipzig, Germany.
    Eruptive vellus hair cysts occur sporadically, hereditarily or in association with other diseases due to developmental anomalies of vellus hair follicles. Here, we report on a 41-year-old male with multiple vellus hair cysts of the forehead, who was successfully treated three times with a non-ablative, non-fractional 1540 nm Er:Glass laser on one side of his face, and with an ablative non-fractional 2940 nm Er:YAG laser on the other side, at intervals of 6-12 weeks. Over the whole treatment period of about 9 months, we could observe a marked reduction in the total number of cysts. Read More

    A Case of Multiple Pilosebaceous Cysts.
    Case Rep Dermatol 2010 Jul 2;2(2):116-119. Epub 2010 Jul 2.
    Department of Dermatology, Kinki University Faculty of Medicine, Osakasayama, Japan.
    Multiple pilosebaceous cysts include the entities of steatocystoma multiplex and eruptive vellus hair cysts (EVHCs). Multiple pilosebaceous cysts are proposed to be one entity originating in the pilosebaceous duct, since steatocystoma multiplex and EVHCs are frequently present concomitantly and are caused by a cystic change in the same pilosebaceous duct. Here, we describe a patient with yellowish papules, 3-8 mm in diameter, on the neck and skin-colored or light-brown papules, 1-3 mm in diameter, on the neck, chest and upper abdomen. Read More

    Follicular hybrid cysts with infundibular, isthmic-catagen, and pilomatrical differentiation: a report of 2 patients.
    Ann Diagn Pathol 2006 Apr;10(2):110-3
    Department of Pathology, Baylor University Medical Center, Dallas, TX 75246, USA.
    The term hybrid cyst was originally coined to describe combination follicular cysts with both epidermoid and trichilemmal (pilar) epithelial zones, separated by an abrupt transition. The concept has since expanded to include many different combinations of pilosebaceous unit differentiation. Entities previously reported also include infundibular and pilomatricomal cyst, trichilemmal and pilomatricomal cyst, eruptive vellus hair cyst combined with steatocystoma or trichilemmal cyst, and trichilemmal, sebaceous, and pilomatricomal cyst.

    Eruptive vellus hair cyst in patients with chronic renal failure.
    Dermatology 2004 ;208(1):67-9
    Department of Dermatology, National Defense Medical College, Tokorozawa, Japan.
    Two cases of eruptive vellus hair cysts associated with chronic renal failure are reported. Histologically the lesions of both cases showed cystic structures in the dermis lined by squamous epithelium which contained varying amounts of vellus hair shafts. Immunohistochemical studies using monoclonal anti-AGE (advanced glycation end product) antibody demonstrated that keratinous materials within the cystic structures were immunoreactive to the antibody, whereas those of cystic lesions (epidermal cyst, eruptive vellus hair cyst, steatocystoma multiplex, trichofolliculoma and trichilemmal cyst) seen in otherwise healthy individuals were negative.
