Health Utility Measures Among Patients with Androgenetic Alopecia After Hair Transplant.

BACKGROUND: Hair loss causes significant psychosocial distress to patients. Health utility measurements offer an objective, quantitative assessment of health-related quality of life (QOL). METHODS: We performed a prospective cohort study on patients with hair loss between January 1, 2018 and December 31, 2020. Patient metrics were compared with layperson perception of alopecia, prospectively collected between August 1 and December 31, 2017. Health utility measures were quantified using the visual analog scale (VAS), standard gamble (SG), and time trade-off (TTO) in quality-adjusted life-years (QALYs) and relative to the minimal clinically important difference (MCID). Bonferroni correction to the significance threshold was performed. RESULTS: Thirty-one patients with alopecia were compared with 237 laypeople. Patient metrics for female hair loss were all significantly lower than laypeople measures (VAS QALYs 0.65 ± 0.21 vs. 0.83 ± 0.18, p = 0.0001). Mean SG QALYs were lower for patients in the male alopecia state (0.86 ± 0.23 vs. 0.96 ± 0.12, p = 0.0278). Post-hair transplant improvement in TTO was significantly greater for patients (+ 0.08 ± 0.12 vs. + 0.02 ± 0.09, p = 0.0070) and significantly more often exceeded the MCID (45.2% vs. 16.9%, p = 0.0006). CONCLUSIONS: Alopecia negatively impacts QOL, and the true patient experience is more taxing than what is perceived by laypeople. Hair transplantation improves QOL more for male patients than common perception. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Comparison of Shave and Punch Biopsy Utilization Among Dermatology Practices.

In 2019, the 2 Current Procedural Terminology (CPT) codes for skin biopsies were replaced with 6 new CPT codes to allow for technique specification and differential reimbursement. We sought to evaluate whether the concurrent decrease in reimbursement for shave biopsies and increase in reimbursement for punch biopsies led to utilization changes. We examined shave and punch biopsies submitted for pathologic examination at 3 academic centers in May 2018 and May 2019. We performed χ2 tests to evaluate for changes in the ratio of biopsy utilization over time, with subgroup analyses by practice setting and provider type. Totals included 11,785 (12.11% punch) and 11,291 (12.08% punch) biopsies submitted in May 2018 and May 2019, respectively. Our results demonstrate small yet important changes in biopsy use patterns within the context of recent reimbursement changes when analyzing academic and private practices separately. Although small in magnitude, this change in behavior may have a substantial impact when extrapolated to behavior across the nation.

Histologic and clinical cross-sectional study of chronic hair loss in patients with cutaneous chronic graft-versus-host disease.

BACKGROUND: While scalp alopecia represents a distinctive feature of chronic graft-versus-host disease (cGVHD), little is known about the clinical and histologic presentation of hair loss. OBJECTIVES: We sought to classify the clinical presentations and histologic findings of chronic hair loss in patients with cutaneous cGVHD. METHODS: A prospective cohort of 17 adult hematopoietic cell transplantation (HCT) recipients with cutaneous cGVHD was enrolled. Dermatologic examinations were performed, and punch biopsy specimens of the scalp were obtained. Biopsy specimens were analyzed with hematoxylin-eosin and immunohistochemical stains in all cases and fluorescence in situ hybridization analyses in specific cases. RESULTS: Clinically, 4 patterns of hair loss were described-patchy nonscarring (41.2%), diffuse nonscarring (11.8%), diffuse sclerotic (11.8%), and patchy sclerotic (5.9%). The location of the inflammatory infiltrate on hematoxylin-eosin-stained specimens correlated with the hair loss pattern patients had clinically, with cell populations around the bulb and bulge in nonscarring and sclerotic cases, respectively. Fluorescence in situ hybridization studies in female cGVHD patients with male donors demonstrated green Y chromosomes limited to the area of the hair follicle affected by inflammatory cells. CONCLUSION: This study describes the various clinical and histologic subtypes of long-standing alopecia in adult cGVHD patients and suggests that this alopecia may be a direct manifestation of cGVHD of the hair follicle.

Indurated purple plaques on the scalp.

Cutaneous epithelioid angiosarcoma is a rare neoplasm of vascular endothelial cell origin that can mimic a cutaneous lymphoma, metastatic carcinoma, or Kaposi sarcoma. It is one of the most malignant cutaneous tumors and early diagnosis is essential, as the tumor metastasizes quickly. We describe a 75-year-old man who presented with three tender, indurated violaceous plaques on his scalp. Biopsy revealed a poorly circumscribed infiltrate extending into the subcutaneous fat, composed of atypical epithelioid cells lining vascular spaces. We provide a brief review of the clinical presentation, histopathologic features, differential diagnosis, and management of this rare tumor.
