Dermoscopic features of post kala azar dermal leishmaniasis

Abstract

Eyelash poliosis has been described as an atypical manifestation of metastatic melanoma recurrence in one patient who underwent primitive lesion excision three years before; similarly to our case, the primary melanoma was distant from the area of poliosis. 7 The peculiarity of our case is that eyelash poliosis manifested as first clinical sign of an undiagnosed melanoma, not adjacent to the localization of the whitening in contrast to what reported so far, nor a consequence of medication use.Concluding, we want to underline that even if whitening of hair including eyelashes is more often associated with regression during immunotherapy for metastatic melanoma, it could be a relevant manifestation of melanoma development and progression itself.

Dermoscopy of Infectious Dermatoses (Infectiouscopy) in Skin of Color—A Systematic Review by the International Dermoscopy Society “Imaging in Skin of Color” Task Force

“…The presence of the latter finding was confirmed by Swarnkar et al , who observed it in hypopigmented macules, papules and nodules. 71 In line with another report, Swarnkar et al also found yellow-orange structureless areas, thought to correspond to dermal granulomas [ 69 , 71 ].…”

“…Three reports have investigated dermoscopy of post-kalaazar dermal leishmaniasis (PKDL) [69][70][71]. The first description by Jha et al reported erythema and follicular plugs [70].…”

Dermoscopy of skin parasitoses, bites and stings: a systematic review of the literature

“…Post‐kala‐azar dermal leishmaniasis (PKDL) is the cutaneous sequela of visceral leishmaniasis and presents as progressively increasing hypopigmented macules, erythematous papules and nodules, and/or facial erythema 124 . Dermoscopy of PKDL has been infrequently reported.…”

“…Thakur et al described the presence of yellow structureless areas with reduced pigment network and preservation of appendages in two patients. 124 The preservation of appendages was highlighted by the authors as a possible clue to help differentiate PKDL from lepromatous leprosy (where a loss of appendages is appreciated). Finally, Jha et al 125 described yellow tears corresponding to follicular plugs with surrounding erythema in their patient.…”
