A 72-year-old female presented to skin OPD with an asymptomatic lesion over her right palm since 10 years. There was no history of bleeding or discharge from the lesion and no history of friction over the site except for the routine daily activities. The patient had no other associated comorbidities. On examination, a single sessile, soft skin, colored lesion 0.5×0.5 cm in size was present on proximal part of proximal phalanx of palmar aspect of right middle finger ([Figure 1]). Routine hematological investigations including lipid profile, complete blood counts, and blood sugars were within normal limits. Her height was 150 cm and weight was 51 kg. Clinically, diagnosis of acrochordon was made. Excision biopsy was performed, which on histopathology showed hyperplastic epidermis with orthokeratosis, parakeratosis, hypergranulosis, and papillomatosis ([Figure 2]a). The underlying dermis showed ecstatic and dilated vascular channels in an edematous stroma ([Figure 2]b), suggesting diagnosis of acrochordon.

Acrochordon or fibroepithelial polyp, commonly known as a skin tag, is a benign, pedunculated, or sessile papillomatous growth of skin mainly composed of epidermal and stromal component. Its size varies between 1 and 5 mm and usually involves intertriginous areas like the neck, axilla, or groin [1], which is in contrast to our case, where it was present over proximal phalynx of palmar aspect of right middle finger. We could not find any case of acrochordon on palms or soles even after extensive search. Acrochordon has been reported to have an incidence of 46% in the general population [2]. Nearly 60% of individuals acquire them by the age of 69 years [3]. Acrochorda are harmless and typically painless and do not grow or change over time [4]. The surface of an acrochordon may be smooth or irregular in appearance and is often raised from the surface of the skin on a fleshy stalk called a peduncle. It can affect any age, including infants.

Three types of acrochorda have been described [4]:
  1. Papules that are small, furrowed, measuring 1–2 mm in width and height, and present mostly on the neck and the axillae.
  2. Filiform lesions, single or multiple, measuring 2 mm in width and 5 mm in length occurring elsewhere on the body.
  3. Large, pedunculated tumor or nevoid, baglike, soft fibromas which occur on the lower part of the trunk.

The etiology of skin tags is not well understood. They are thought to occur because of frictional rubbing between skin surfaces as they are commonly found in skin creases and folds [2]. There are reports of skin tags over penis following chronic use of condom catheter. It has been proposed that these are secondary to the negative pressure of the condom catheter and the irritation and inflammation associated with its long-term use [5].

Possible role of trauma in skin tags was studied by El Safoury et al. and they suggested that mast cells through the release of mediators like tumor necrosis factor-α and tumor necrosis factor-related apoptosis-inducing ligand might play a role in the pathogenesis of skin tags in response to trauma [6]. Dianzini et al. [7] suggested role of low-risk human papillomavirus 6 and 11 in pathogenesis of acrochorda.

They are usually seen alone but are sometimes associated with colonic polyps (Gardner syndrome), diabetes, obesity, hyperlipidemia, insulin resistance, acromegaly, Birt–Hogg–Dubé syndrome, and polycystic ovary syndrome [4]. They appear or increase in number when a patient is gaining weight, having insulin resistance, or during pregnancy [1]. Shenoy et al. [8] have reported significantly high prevalence of metabolic syndrome in patients with skin tags. In our case, no such association was observed.

Skin tags are diagnosed generally by clinical features. Over common sites like neck, groin, and axillae, it needs to be differentiated from conditions like fibrokeratoma, accessory tragus, pedunculated seborrheic keratosis, pleomorphic fibroma, and polypiodal intradermal melanocytic nevus. Palm is an unusual site for skin tag to occur where one need to think of cutaneous horn, common warts, or seborrheic keratosis in differential diagnosis. Histopathology helps to rule out other conditions. Microscopically, an acrochordon consists of a fibrovascular core, sometimes also with fat cells, covered by an unremarkable epidermis or by acanthotic, flattened, or frond-like epithelium [4].

Treatment of skin tags includes cryotherapy or surgical excision.

Our presented case shows acrochordon occurring over the ventral aspect of right middle finger, which is an unusual site for presentation.
