We describe a case series of salt and pepper pigmentation with some unusual features. microscopy of the perifollicular stroma showed that cathelicidin colocalized with the PREF1 preadipocyte marker (Fig. The colour of skin and hair is mainly due to the amount of brown melanin pigment mixed with blue (from reduced haemoglobin ), red (from oxyhaemoglobin) and yellow (from carotenoids in the diet). The keratin plugs correspond to hyperkeratosis that is more prominent in follicular opening, the perifollicular red dots to dilated vessels and erythrocyte extravasation in perifollicular area. Conclusion. R. Y. Conclusions: Perifollicular hypopigmentation is a cause of variegate pigmentation and irregular border in melanocytic nevi.

Farah, MD, University of Minnesota, Department of Dermatology, 516 Delaware St SE, MMC 98, Minneapolis, MN 55455 ( rfarah@umn.edu ). Therefore, though perifollicular pigmentation is preserved in the lesional skin in most cases of vitiligo, PFD seen on dermoscopy may paradoxically indicate impending vitiligo especially in a high-risk case e.g. March 26, 2011. Follicular depigmentation. Loss of pigment in the hair follicles, as compared to the surrounding skin. It represents an early sign of active vitiligo, but can also be found in other causes of hypopigmentation. 2C), a strong indicator of reactive adipogenesis, because CAMP is highly ex-pressed by preadipocytes during early differentiation into adipocytes (10). Fig. A pattern of depigmentation with residual reservoirs of perifollicular pigment have been noted, and this was signifying focally active or regimenting vitiligo. Close. Herlitz (EB Lethalis) 2.

This may be due to the richer capillary network that may warm the perifollicular skin and preserve melanogenesis producing the perifollicular pigment retention in systemic sclerosis.1,2 Both cellular and humoral immune factors in combination with external factors such as trauma or inflammation may trigger the destruction of melanocytes.3 Moreover, various physical factors Dermoscopy of facial (and extra-scalp in general) discoid lupus erythematosus shows different features according to the stage of disease, with erythema, perifollicular whitish halo, follicular keratotic plugs, red dots and white scaling being the most common/characteristic features of early lesions, and whitish structureless areas, hyperpigmentation (honeycomb Rapid activation and division of hair follicular cells cause the hair shaft to grow longer and the extracellular matrix components to increase in concentration. strings of text saved by a browser on the user's device. ), or their login data.

From Journal of Reproductive Fertility, 1982, 66, 715-716. Based on the criteria given by Coup, a diagnosis of nevus depigmentosus was made. Understanding the skin biology amongst different races is fundamental if you are a dermal therapist, nurse injector, #aesthetician or dermatologist . Pigment accentuated around the hair follicles. Blond/red hair: predominance of pheomelanin *Data from Ref. Complete asymmetry suggests the lesion may be malignant, but may also be seen in some atypical naevi. Thus basal cells are lost in the disease process. 15 This residual perifollicular pigmentation had been observed in (91.9%) of patients with progressing vitiligo and (62.9%) of those with stable vitiligo, 16 and this can be considered as characteristic for vitiligo Perifollicular pigmentation is the first target for topical vitamin C derivative ascorbyl 2-phosphate 6-palmitate (APPS): randomized, single-blinded, placebo-controlled study.

Pigment cells are larger & react briskly to light, lasers, & chemicals. Delicate Pigment Network. Whereas in BP, there is complete loss of epidermis with partial loss of basement membrane. Physical examination disclosed perifollicular hemorrhages and extensive ecchymoses with increased pigmentation involving the lower extremities (Figure 1). In systemic sclerosis, vitiligo-like depigmentation of salt and pepper pigmentation usually spares the perifollicular areas. 1 (2022) These were further treated with PUVA/PUVASOL. The pigmentation may extend to the chest, neck, and scalp, and occasionally involves the hands and forearms. [4] has shown significant association between dermoscopic features of dots with/without globules to moderate-severe pigment incontinence on HPE. dyspigmented Easy to pull out Corkscrew hairs History of night blindness (also impaired visual recovery after glare) Photophobia, blurring, conjunctival inflammation Hair shaft abnormalities . Spermatozoa in an abdominal lymph node after vasectomy in a man. Perifollicular inflammation was almost a constant feature in early cases and showed a significant correlation with perifollicular fibrosis (P = 0.048), which was more marked with thickening of the follicular sheath in advanced cases. Smaller pigmented macules, often perifollicular, lie beyond the indefinite margin. The last decade has repeatedly shown that this is The irregular extensions are seen as pseudopods at the periphery with perifollicular pigmentation and there is the absence of perifollicular hyperpigmentation . By dermoscopy, symmetry is evaluated in terms of pigment pattern (colour and/or structure). B Diagrams showing the hair regeneration process. EBS Muscular Dystrophy 5. The repigmentation assessed by percentage value range from 0- 100% where the 100 % means full repigmentation, the value is a result of an equation where the estimated percentage of marginal repigmentation add to ( remaining area (%) plus estimated percent of perifollicular pigmentation in the remaining area(%) divided by 100) Non-Herlitz (Generalized Atrophic Benign EB) 3. 9, No. The panels are of the same magnification to show the difference in size. 22.3), perifollicular and perilesional hyperpigmentation (Fig. (E) Interfollicular scales.

These nodules dermoscopically showed irregular dots and negative pigment network (Fig. Share sensitive information only on official, secure websites. Dystrophic EB. The dermoscopy criterion for suspicion was pigmentation of the perifollicular openings over a lighter brown structureless pigmentation. Dermoscopy revealed a homogeneous clear brown area with a delicate pigment network (Fig. Wnt1 induction is linked with melanocyte stem cell differentiation in hair follicles on lentigo solaris, which is a hyperpigmentation skin disorder in sun-exposed area. The Infona portal uses cookies, i.e. Besides less common psoriatic lesions also include the follicular variant with perivascular and perifollicular inflammatory infiltrates and follicular plugging. It can be seen in some alopecias, but also represents the first sign of re-pigmentation in vitiligo. split: Basement Membrane (lamina lucida) types: 3 1.

A comparative dermoscopic and reflectance confocal microscopy study of naevi and melanoma with negative pigment network. Hallopeau-Siemens (recessive DEB - HS) 2. Re-pigmentation in human vitiligo occurs in different clinical patterns, of which the most frequent re-pigmentation pattern is the perifollicular type, which indicates that hair follicles are the main melanocyte reservoir for this pattern.

Asymmetrical pigmented follicular openings are curved or crescent-shaped areas of pigment partially surrounding the adnexal openings of the face. Asymmetrical pigmented follicular openings are seen through the dermatoscope as pigmented crescents at the periphery of a follicle.

White structureless areas (absence of Brownish-gray pigmentation develops quite rapidly over the greater part of the face but is more intense on the forehead and temples. R. Y. Larger prospective studies determining whether perifollicular hypopigmentation precedes end-organ involvement and whether specific patterns associate with internal organ involvement are needed.
