Hailey–Hailey disease (HHD) is a blistering disease caused by mutation in ATP2C1 gene with autosomal dominant inheritance. The usual age of presentation is late teenage or in adulthood (30s and 40s). Delayed diagnosis is common, especially if the patient's lesions respond to topical steroids and antifungals. We present a clinically misdiagnosed case in an elderly female and attempt a clinic-dermoscopic-histological correlation.
A 77-year-old female presented with intensely pruritic lesions over the groins and perianal area since 2 years. She was previously diagnosed as a case of tinea cruris et corporis and had received repeated courses of oral and topical antifungals along with antihistamines and intermittent topical steroids for a variable period. She was a known case of rheumatoid arthritis since 15 years and was on prednisolone 10 mg daily, along with oral methotrexate 7.5 mg/week since 3 years. There was no other significant past, personal, or family history.
The clinical examination revealed ill-defined erythematous to violaceous macerated plaques over bilateral groins and labia majora extending onto its inner aspect [Figure 1]a and [Figure 1]b. Similar plaques were noted over the perianal area [Figure 1]c. Few erosions were noted over the plaques, which were attributable to the intense pruritus. The remaining dermatological examination was normal. Considering the violaceous appearance of the lesions, a clinical diagnosis of inverse lichen planus with genital involvement was made.

Dermoscopy of the lesions performed using DermLite DL4N in polarized mode showed linear red to brown linear ulcers with sharp angulated margins along with whitish macerated edges on a pinkish-white background. Arborizing telangiectasia were seen in the periphery [Figure 2]. Histopathology showed acantholysis of the whole epidermis with classical dilapidated brick wall appearance with acanthosis and dyskeratosis, features diagnostic of HHD [Figure 3]a and [Figure 3]b.

The diagnosis was intriguing considering the late age of onset, absent family history, ongoing immunosuppressive treatment, and absence of seasonal variation.
HHD (familial benign pemphigus) is an autosomal dominant genetic disorder characterized by painful blistering and erosions affecting the flexural areas. The onset is usually between third and fourth decade of life; however, it may manifest in early childhood or just after puberty.
Although the diagnosis is straight forward in most cases, the presentation was quite unusual in our case considering the age of onset being over 70 years.
The dermoscopic finding of pink and white areas in a cloud-like pattern described in HHD  was not a prominent feature in our case; however, some interesting points in dermoscopic-histopathological correlation are listed in [Table 1].,

The sharp angulated borders of the linear ulcers are considered a marker of dermoscopic Nikolsky. The whitish margins of the fissures can be attributed to the hyperkeratosis and acanthosis along with the associated maceration owing to the intertriginous location of the lesion. Hence, the characteristic clinical feature of Hailey and Hailey-fissures or rhagades which may not be visible to the naked eye, as in this case, can be better visualized using a dermatoscope can aid the diagnosis earlier.
In conclusion, we present a rare case of late HHD with no associated family history in a patient of rheumatoid arthritis on immunosuppressive therapy. Although the characteristic histopathological picture clinched the diagnosis, we wish to highlight the importance of noninvasive dermoscopy in helping to diagnose the condition early.
