Our aim was to study the evolution of clinical pattern of parthenium dermatitis. Patients with clinical picture consistent with parthenium dermatitis for 3 years or more along with positive patch test to parthenium were studied. Patients were questioned regarding the site(s) of dermatitis at the onset and change in localization in the following years. Patients were classified into airborne contact dermatitis, chronic actinic dermatitis (CAD) pattern or mixed pattern dermatitis. There were 74 patients (49 men and 25 women) with an age range of 22-70 years and the mean duration of 7.7 years. 60 (39 men and 21 women) patients had airborne contact dermatitis, 5 mixed pattern and 9 CAD pattern at the onset. Of the 60 patients with airborne contact dermatitis, 27 (19 men and 8 women) changed to CAD pattern and 11 (6 men and 5 women) to mixed pattern after an average period of 4.2 years. Of the 19 patients photopatch-tested with parthenium, 3 showed photoallergic reaction and the other 3 showed photoaggravation. Our results suggest that the clinical pattern of parthenium dermatitis undergoes a significant change after the onset, i.e. progresses from airborne contact dermatitis to mixed pattern or CAD pattern.

“…48 One possible source of a contact exposure is chrysanthemums, members of the Compositae family, which are a well-known cause of occupational dermatitis, including irritant contact, phototoxic, and allergic contact dermatitis. [49][50][51] The histological findings of compact hyperkeratosis, interface dermatitis, dermal melanosis, and a persistent perivascular lymphocytic infiltrate supports the contention of irritant dermatitis having caused melanin incontinence and clinical hyperpigmentation. 4,51 However, as pigmented contact dermatitis is a rare manifestation of hand dermatitis, 48 it indicates that this woman has a hyperchromatic tendency, which caused volar melanocytes to respond to irritation and inflammation by increasing melanin production.…”

Volar melanotic macules are asymptomatic, tan-brown to brownish-black macules found on the palms, fingers, soles, and/or toes of dark-skinned individuals and are infrequently reported in light-skinned individuals. Herein, we report the acquisition of multiple, brownish-black volar digital macules in a 63-year-old white woman and avid gardener that were noted after the onset of pruritic, chronic hand dermatitis over a 10-month period. She was healthy without any medical conditions or medications. No family history of intestinal polyposis or mucosal melanosis existed. At presentation, she had less than 20 brownish-black, 2- to 10-mm irregular macules over the volar aspect of the thumbs and index fingers, left greater than right hand, associated with erythema, scale, and a negative potassium hydroxide examination. In addition, she had melanotic macules of her lips, buccal mucosa, and conjuctiva. No nail or anogenital macules were found. Biopsy demonstrated a region of epidermal hyperplasia, hyperkeratosis, and interface dermatitis associated with melanophages and sparse lymphocytic infiltrate. Melanin staining revealed diffuse pan-epidermal hypermelanization, dermal melanin, and dendritic melanocytes, which expressed HMB-45. After 1-year follow-up and treatment with topical corticosteroid, the volar macules have faded to tan brown. Based on the location, avocation, and coexisting mucosal melanotic macules, an irritant phytodermatitis with postinflammatory hyperpigmentation was diagnosed in the setting of Laugier-Hunziker syndrome-a disorder denoted by macular hyperpigmentation of nail, volar, and/or mucosal surfaces in healthy adults. Volar melanotic macules can also complicate 5-flourouracil therapy, tinea pedis, and other inflammatory disorders; be associated with acral melanomas; or represent a cutaneous manifestation of systemic disease such as Addison disease, Peutz-Jegher syndrome, Leopard syndrome, Carney syndrome, AIDS, and neurofibromatosis.
