“…Although a facial papule displaying arborizing vessels and shiny white structures under dermoscopy is highly suggestive of basal cell carcinoma, the patient’s clinical history and the presence of numerous identical lesions raised the clinician’s suspicion for multiple familial trichoepithelioma. Importantly, each lesion had a similar dermoscopic morphology that was consistent with features that have previously been described for desmoplastic trichoepithelioma and solitary trichoepitheliomas, namely, arborizing vessels and milia-like cysts [10,11]. The presence of milia-like cysts in dermoscopy was correlated with the presence of keratin cysts in the histopathology (Figure 3).…”

Trichoepitheliomas are uncommon benign adnexal neoplasms that originate from the hair follicles. Multiple familial trichoepithelioma constitute an autosomal dominant disease characterized by the appearance of multiple flesh-colored, symmetrical papules, tumors and/or nodules in the central face and occasionally on the scalp. Although clinical diagnosis is usually straightforward in light of the family history and naked-eye examination, dermoscopy may aid in its confirmation. Dermoscopy of each papule revealed in-focus arborizing vessels, multiple milia-like cysts and rosettes amidst a whitish background.In a patient with multiple facial papules revealing a dermoscopic appearance described above, the diagnosis of sporadic or familial multiple trichoepithelioma should be considered.

“…We report the rare event of a trichoepithelioma arising within a CMN on the back of a male adult. Although dermoscopy should suggest distinguishing features, our findings were quite different and not reassuring, confirming that sometimes only histopathology is capable to resolve the quandary [5][6][7].…”

“…Moreover, the raised papule dermoscopy was not suggestive of TE [5][6][7], showing a homogenous brownish pigmentation instead of pearly to white hue, without arborizing vessels at the periphery, considered characteristic of TE lesion. Different presentation might depend on the dense background pigmentation of the CMN, instead of the minimally pigmented dermal nevi previously described.…”

“…Rates of blue-gray areas at orf and milker’s lesions have not been determined as significant ( p = 0.373). Dermoscopic formations similar to those structures are named as blue-gray globule at basal cell carcinoma and trichoepithelioma [ 14 , 15 ]. The blue-gray area has been observed at a 20% rate in a study in which 10 pilomatrixoma cases have been evaluated [ 10 ].…”

IntroductionOrf and milker’s nodule are zoonotic cutaneous diseases generated by parapoxviruses. Contribution of dermoscopy to the diagnosis of these diseases has not been studied in the medical literature as to our knowledge.AimTo investigate whether dermoscopy is a valuable diagnostic tool in orf and milker’s nodule diagnosis or not.Material and methodsIn this study, macroscopic and dermoscopic features have been evaluated by including 46 lesions of 32 patients who have orf and milker’s nodule.Results56.5% (26) of lesions were orf, while 43.5% (20) of lesions were milker’s nodule (MN). Non-vascular dermoscopic structures have been determined as follows: blue-gray area (23.1% of orf, 35% of MN), orange-yellow streaks (19.2% of orf, 19.2% of MN), grayish-whitish streaks (26.9% of orf, 55% of MN), central yellow-white area (26.9% of orf, 35% of MN), crust (46.2% of orf, 40% of MN), erosion-ulceration (69.2% of orf, 55% of MN), yellow-white globule (11.5% of orf, 15% of MN), and yellow-white ring (57.7% of orf, 35% of MN). Limitations: Lack of PCR analysis, based of patient anamnesis types of orf and milker’s nodule.ConclusionsNo significant dermoscopic differences have been determined between orf and milker’s nodule patients’ lesions. In our opinion, dermoscopy may be a useful tool to develop diagnosis of these diseases.
