Erythromelanosis Follicularis Faciei et Colli (EFFC) and Erythroses Pigmentosa Mediofacialis (EPM) are considered to be the disorders of abnormal follicular keratinization characterized by a triad of hyperpigmentation, erythema, and keratotic follicular papules. Herein, we report a young female with a features of both in association with generalized keratosis pilaris which is a rare co-occurrence, diagnosis of which was confirmed by dermoscopy and histopathology.

A 16-year-old female reported with multiple asymptomatic elevated lesions associated with darkening of skin which appeared first over the sides of cheeks, upper part of ear and gradually extended over the neck since 4 years. Similar lesions were also seen over central part of face since 2 years. Patient denied history of topical application and photosensitivity. Her past, personal, and family history was insignificant. Cutaneous examination revealed bilaterally symmetrical follicular micropapules associated with well-demarcated erythema and hyperpigmentation over the pre-auricular region, pinnae of ear and neck [Figure 1]a and [Figure 1]b. Forehead, perinasal, peribuccal region, and chin also showed lesions of similar morphology [Figure 2]. In addition, patient had keratotic papules over bilateral extremities, back, chest, abdomen, and thighs suggestive of generalized keratosis pilaris [Figure 3]a, [Figure 3]b, [Figure 3]c, [Figure 3]d. On diascopy of facial lesion erythema disappeared but pigmentation persisted. Dermoscopy using 3 Gen Dermlite DL4 (CA, USA) 10 × polarized mode, from cheeks revealed multiple small whitish rounds with keratotic follicular plugs surrounded by gray spots in a background of brownish discoloration suggestive of EFFC [Figure 4]a. Forehead lesion on dermoscopy showed numerous dilated follicles with keratotic plugging, perifollicular erythema, and scaling suggestive of EPM [Figure 4]b. Dermoscopy of the lesion from upper arm showed coiled hair, keratotic plugs, perifollicular erythema, and scaling suggestive of keratosis pilaris [Figure 4]c. Skin biopsy (one from cheek and another from forehead) with H and E staining revealed follicular hyperkeratosis with acanthosis with increased pigmentation in the basal layer. Dermis showed superficial perivascular lymphocytic infiltrate [Figure 5]a and [Figure 5]b. Based on clinical, dermoscopy and histopathology a final diagnosis of coexistent EFFC and EPM in a patient of generalized keratosis pilaris was made. The patient was counselled and started on topical tretinoin 0.025% cream and sunscreen for face and an emollient for the body. After 8 weeks of treatment patient showed only mild improvement and is under regular follow-up.{Figure 1}{Figure 2}{Figure 3}{Figure 4}{Figure 5}

EFFC is an unfamiliar syndrome described by Kitamura, in 1960, with well-demarcated erythema, telangiectasia, hyperpigmentation, and follicular papules primarily on lateral aspect of the face, with an extension on to the lateral half of the neck, thus the name et colli (in Latin”et”=”and”,”colli”=”neck”). It affects patients of all ethnic group but majorly seen in Asian or Middle Eastern men.[1] The male to female ratio is observed to be 2:1.[2] However, it is increasingly reported in female patients as noticed in our case.[3] EPM as described by Brocq, is erythematous to hyperpigmented, rough skin over midline of the face. It is synonymously called as erythrose pigmentaire faciale, dermatose pigmentée médiofaciale, erythrosis pigmentosa peribuccalis, erythrosis pigmentata faciei, erythromelanosis follicularis faciei and erythrosis pigmentosa faciei colli.[4] The etiology of EFFC is multifactorial and includes genetic (autosomal recessive) and hereditary components.[5] Previous data suggest spontaneous mutation in EFFC.[6] Tuzun and Wolf et al. postulated that EFFC to be a chromosomal instability syndrome.[7] It is hypothesized that various environmental factors such as cosmetics, ultraviolet radiation, and topical formulations can cause hyperpigmentation over the period of years. Dermoscopy of EFFC shows multiple round whitish areas with follicular plugs, some shows central hair, surrounded by blue gray spots or peppering in a reddish-brown background.[8] Dermoscopy of EPM includes follicular dilatation with yellowish keratotic plugs, perifollicular erythema, and scaling surrounded by slate-gray globules.[9] Histology of EFFC and EPM is similar and shows follicular hyperkeratosis, increased basal layer pigmentation, and incontinence of melanin pigment with dermal melanophages. Dermis shows perivascular and periadnexal lymphocytic infiltrate with vasodilatation.[8] EFFC has been found to be associated with keratosis pilaris of different body parts which postulated that EFFC is a variant of keratosis pilaris.[3],[4],[6],[7],[10],[11] Juhlin et al. has reported a single case of EFFC and EPM occurring in a 34-year-old female postulating that the two conditions are same.[12] Our case is unique since she had concurrent EFFC, EPM, and generalized KP. It can be stated that both EFFC and EPM are etiologically same conditions manifesting at different sites. Dermoscopy plays an important beside tool to identify these entities. Differential diagnosis of EFFC and EPM includes ulerythema ophryogenes, atrophoderma vermiculatum, Riehl's melanosis, poikiloderma of Civatte, tricostasis spinulosa, lichen spinulosus [Table 1]. Treatment of EFFC and EPM is same but unsatisfactory. Various topical keratolytics such as tretinoin, glycolic acid, salicylic acid (20–30%), urea, ammonium lactate, vitamin C can be used assuming it to be a disorder of keratinization. Oral isotretinoin (0.1–1 mg/kg/d) can be tried for extensive involvement. Topical tacalcitol ointment was found to be a successful therapeutic option for EFFC in recent years.[13] Multiple sessions of long-pulsed dye laser for erythema and Q-switched Nd: YAG laser (1,064 nm) for hyperpigmentation are mentioned in the treatment of EFFC by Li et al.[14] EFFC and EPM are underreported disorders which can be easily diagnosed with the help of a dermoscope. Also, it is the rarity of EFFC and EPM associated with generalized KP which prompted us to report this case.{Table 1}
