A 5-year-old male child, third born of second degree consanguineous marriage presented with complete alopecia over the scalp since the age of 2 months. He had scanty hairs at birth but gradually lost all scalp hair with sparse hairs over the eyebrow and eyelashes. There was no history suggestive of abnormalities in hearing impairment, delay in dentition, intolerance to heat, decreased sweating, atopy, and delayed milestones. The child had been hospitalized during infancy for recurrent lower respiratory tract infections and was diagnosed with situs inversus and dextrocardia.
On examination, there was alopecia over the scalp with papules with sparse hairs over the eyebrows and eyelashes [Figure 1]. Multiple, discrete skin colored papules were seen over the trunk, upper and lower extremities. Teeth, nails, and mucosa were normal.

Biopsy from a papule over the forearm revealed acanthosis and multiple epidermal keratin cysts. Biopsy from the scalp showed a markedly decreases follicular counts, few vellus follicles in the mid-dermis with sparse perifollicular lymphocytic infiltrate and follicular plugging with no terminal hairs [Figure 2]. Chest radiograph [Figure 3] and transthoracic echocardiography showed situs inversus with dextrocardia. Based on clinical and histopathological findings, a diagnosis of Atrichia with papular lesions (APL) was made with rare association of situs inversus and dextrocardia.

APL (OMIM#209500) is a rare form of irreversible alopecia, autosomal recessive condition. Mutations in the human HR gene located on chromosome 8p21.2 which encode a putative single zinc-finger transcription factor protein believed to regulate catagen remodeling in the hair cycle is implicated. The hair matrix cells in APL undergo a premature apoptosis, the hair bulbs, and dermal papillae remain stranded in the dermis, and messages between dermal papillae and the stem cells in bulge are not transmitted, so no further hair growth occurs.
In individuals affected, normal hairs are present at birth, but these neonatal hairs are usually shed within the 1st months of life and are never replaced. The shedding of the hair occurs during the first 2 ± 3 years of life. Hairs are typically absent from the scalp, axilla, and body especially eyebrows and eyelashes with multiple keratin cysts. These patients have normal development, hearing, teeth, and nails and no abnormalities of sweating. Histology shows an infundibular portion of hair follicles, but the middle and lower portions are replaced by keratinizing cysts. No hair shafts are formed.
The close differential diagnosis includes alopecia universalis, ichthyosis follicularis alopecia and photophobia (IFAP syndrome) and Vitamin D-dependent rickets Type II An induced alopecia. Unlike APL, in IFAP the histopathology shows abortive sebaceous glands, and the total number of hair follicles are not significantly decreased.
Various associations of APL with mental retardation, gastrointestinal polyposis, and delay in bone age have been reported.,, Congenital atrichia associated with situs inversus and mesocardia has been reported. Dextrocardia with situs inversus is a rare condition is estimated to occur one in 6000–8000 live births.
In the present case, the child has congenital papular atrichia associated situs inversus with dextrocardia and also met 4 out of 5 major criteria as proposed by Zlotogorski et al., for APL and later revised by Yip et al. We are reporting this case for this rarity and also systemic association of dextrocardia with situs inversus.
