Background: Sebaceous gland (SG) atrophy is well-documented in scalp lesions of psoriasis and has been considered as an important clue to psoriatic alopecia. However, its specificity for psoriasis has been questioned over the years. We hypothesize that SG atrophy is not specific for psoriasis and looked for its presence in biopsies of seborrheic dermatitis of the scalp. Methods:We conducted a retrospective study of biopsy specimens of clinically suspected and histopathologically proven seborrheic dermatitis of the scalp for changes in SGs between January 1, 2014 and August 6, 2021.Results: SGs lobules were smaller and narrower in five of the six cases of seborrheic dermatitis, and SG atrophy was present in four out of six cases.Conclusions: SG atrophy is observed in seborrheic dermatitis and is not specific for psoriasis or psoriatic alopecia.

The first description of histopathological variants of neurofibroma dates back to 1994. Over the years, many individual case reports elucidating unusual histologic features in neurofibroma have been added to the literature, some of which have defined criteria, with the others falling under the roof of benign neural neoplasms. These unusual features, which sometimes may lead to pauses in identifying a common benign tumor such as neurofibroma. Awareness of these variants may help dermatopathologists avoid misinterpretation. Thus, this review aims to summarize all novel and unusual histopathological variants of cutaneous neurofibroma reported to date, in addition to any unusual variants that we encountered in our practice.

<p class="abstract">Erosive pustular dermatosis of the scalp (EPDS) has been reported as a rare chronic and progressive non-infectious inflammatory condition of the actinically damaged scalp characterized by crusts, erosions and pustules. It tends to occur on the scalp of older people who have usually been treated for diffuse actinic damage and actinic keratoses. The list of possible differential diagnosis is long and includes tinea capitis, folliculitis decalvans, neutrophilic dermatosis, autoimmune vesiculobullous disorders, malignancy etc. Notoriously difficult to treat, these cases tend to be chronic and progressive. These patients often present after repeated treatment to various scalp dermatosis that doesn’t result in clearing instead persistence and perpetuation of the process. A cross sectional prospective study was conducted in department of dermatology in a tertiary care centre in which six cases of EPDS attending outpatient department from 2017 to 2019 were included. EPDS is more common but under recognized condition, hence less cases are reported till date. Increased awareness of and proper diagnosis of this condition changes the approach towards these patients, protects the scalp from involuntary insults and other precipitating factors that hinders with a better outcome.</p>
