Dermatosis neglecta (DN), alternative called as dermatitis neglecta, is a condition which occurs due to inadequate or no frictional cleansing of specific area of the body. DN presents in patients with an underlying physical disability, hyperesthesia, previous trauma, or psychiatric etiology. Although not a life-threatening condition, it is cosmetically bothersome.

We report the case of a 29-year-old male patient, who presented with multiple, hyperpigmented, and velvety plaques over the scalp, especially over the vertex and frontal areas. On enquiry, the patient reported that he had undergone a hair transplant surgery 2 months ago.

He reported that, in the first 2 weeks of the postoperative phase, he followed all the instructions given by the operating surgeon and was doing well. However, in the COVID-19 lockdown time, the patient was not able to schedule a follow-up visit with his hair-transplant surgeon.

Due to fear of damaging of implanted hair grafts, the patient inadequately cleansed the recipient area for about 2 weeks, after which he developed the lesions which were asymptomatic. There were no systemic complaints.

On examination, the patient had multiple, hyperpigmented, verrucous, well-defined waxy plaques diffusely distributed over fronto-parietal area of the scalp [Figure 1].

The patient was counseled regarding the importance of adequate cleansing of recipient area. He was prescribed a mild shampoo for cleansing the scalp regularly. After a few washes, he reported with complete clearance of lesions [Figure 2].

DN, also called unwashed dermatitis, was introduced first by Poskitt et al. in 1995.[1] It occurs chiefly due to the accumulation of sebum, sweat, keratin, and other forms of dirt leading to the formation of a verrucous plaque with adherent corn flake-like scales.[2]

The close differential diagnosis is terra firma forme dermatitis (TFFD), in which there is incomplete keratinocyte maturation, melanin retention, and compaction of scales. Usually, the hygiene is well maintained in TFFD and ill maintained in DN.

There is clearance of lesions of DN by washing with soap and water,[3] while TFFD do not respond to similar action.

Seventy percent isopropyl alcohol-soaked gauze rubbed forcefully completely clears the lesion of TFFD[4] and even DN.

Other main differential diagnoses include acanthosis nigricans, confluent and reticulate papillomatosis, pityriasis versicolor, and dirty neck of atopic dermatitis, all of which can be excluded by alcohol swab test.[5]

DN is an under reported, asymptomatic, and many a times misdiagnosed condition. The awareness of the condition prevents unnecessary laboratory work up. Our case is probably the first ever case reported, where the patient had dermatitis neglecta of scalp after hair transplant operation, which adds a new element to already existing literature of dermatitis neglecta.
