- Follicular streamers (stelae) in scarring and non-scarring alopecia
Follicular streamers are found predominantly in non-scarring alopecia cases Streamers found at deep dermal or subcutaneous levels should be followed and identified at the FU level in order to obtain accurate follicular counts and follicular ratios needed for non-scarring alopecia diagnosis
- The Association between Number of Follicular Stelae and . . .
Alopecia areata (AA) is an autoimmune disease characterized by peribulbar lymphocytic infiltration, follicular miniaturization, catagen telogen follicles, and increased follicular stelae (streamers) in skin biopsies
- Histopathologic diagnosis of alopecia: clues and pitfalls in the . . .
Clues to diagnose histopathologically ‘silent’ (invisible) alopecias, the identification of multiple etiologies, and awareness of the ‘time-factor’ are herein discussed
- Evaluating Scarring vs Non Scarring with Verhoef Van Gieson Elastic . . .
Follicular scars however, are very much a part of scarring alopecia and are associated with elastin clumping, loss and disarray These fine details help differentiate challenging cases
- Follicular streamers (stelae) in scarring and non‐scarring alopecia . . .
Streamers found at deep dermal or subcutaneous levels should be followed and identified at the FU level in order to obtain accurate follicular counts and follicular ratios needed for non-scarring alopecia diagnosis
- Pathology Outlines - Alopecia areata
Immunohistochemical stain for CD3 demonstrates lymphocytes are predominantly T cells There is a catagen telogen shift PAS stain shows normal basement membrane thickness and EVG stain shows preservation of elastic fibers These findings are consistent with alopecia areata
- Polarized Microscopy as a Helpful Tool to Distinguish Chronic . . .
This phenomenon has been referred to as a biphasic pattern on pathology and has been reported for alopecia areata, androgenetic alopecia, and traction alopecia 1 In our experience, polarized microscopy can be helpful in distinguishing cases of long-standing nonscarring alopecia from scarring alopecia
- Histopathology of Scarring and Nonscarring Hair Loss
Alopecia areata and psoriatic alopecia share a marked increase in the catagen telogen percentage, miniaturization, and peribulbar inflammation; however, striking atrophy of the sebaceous lobules is not a feature of alopecia areata
