TTA has been associated with several disorders, such as Phakomatosis Pigmentovascularis. Hair resto-ration surgery using follicular unit transplantation has been a successful treatment modality for TTA. Herein we report such asuccess that was sustained for over six years.1. IntroductionTemporal triangular alopecia (TTA), also known as congen-ital triangular alopecia, is a nonscarring, noninflammatory,circumscribed form of alopecia. The alopecic lesion is usuallyasymptomatic and present at birth or during the first nineyears of life. Lesions are stable and mostly presents withroughly triangular, oval, or lancet-shaped patches in thefrontotemporal region that are characterized by normal hairdensity of vellous hair and normal epidermis. The conditionmostly occurs unilaterally, but bilateral cases (13.5–20%) canoccur [1, 2].TTA has been associated with several disorders [1],one of which is Phakomatosis Pigmentovascularis [1, 3].PPVs are rare syndromes characterized by the coexistenceof pigmentary nevus and a cutaneous vascular malformation[4, 5].Hair restoration surgery using follicular unit transplan-tation has been reported to be a successful treatment fortemporal triangular alopecia, where followup for 16 and 24months postoperatively showedmaintenance of the cosmeticend result [2, 6].2. Case ReportA 25-year-old Caucasian male presented to our practice in2003 complaining of an alopecic scalp lesion in both histemples, which was present since his childhood. The lesionsdid not increase in size nor did it produce any symptoms.Scalp examination revealed an oval, slightly lancet-shaped hypotrichotic patches measuring approximately 8 ×5 cm and 8× 4 cm on the left and right temples, respectively,located supra-aurically (Figures 1 and 2). There were noother signs such as erythema, scaling, or atrophy. A 4mmpunch biopsy was taken from the right-sided patch thatshowed a sparse superficial perivascular and perifollicularinfiltrate of lymphocytes. The hair follicles appeared thinnerand shorter as well as lipoatrophy. The clinical and histopath-ological findings were consistent with TTA. The remainder ofhis cutaneous examination showed the presence of multiplecapillary malformations, mostly involving the right upperlimb, chest, abdomen, and the back (Figures 3 and 4), forwhich the patient is receiving laser therapy. In addition, healso had a bilateral nevus of Ota (Figure 5), and a nevus spiluslocated on the chest (Figure 6). He did not have any otherremarkable cutaneous or systemic findings. The constellation2 Case Reports in Dermatological MedicineFigure 1: TTA, L. temple.Figure 2: TTA, Right temple.Figure 3: Capillary malformation, Rt. Hand.Figure 4: Capillary malformation, back.Figure 5: Nevus of Ota.Figure 6: Nevus spilus, chest.Figure 7: Left side after hair transplant, over six years.of his cutaneous findings (capillary malformation, nevusof Ota, and nevus spilus) led to the clinical diagnosis ofPhakomatosis Pigmentovascularis type IVa.Hair restoration surgery with follicular unit transplanta-tion was oﬀered to the patient as a possible treatment whichhe accepted. The preoperative workout was unremarkable.Patient underwent two sessions one year apart where a 0.7 cm× 5 cm strip was harvested from the occipital donor region,the right half on the first session and the left half on thesecond session. In total, 1449 follicular units were obtainedfrom both surgeries using stereomicroscopic dissection. Thegrafts were placed in the TTA patches with a final densityof approximately 35 FU/cm2. Patient had no postopera-tive complications after either procedures. Sutures fromthe donor area were removed seven and ten days after thefirst and second sessions, respectively. Figures 7, 8 and 9demonstrate the results after six years after the last surgery.Case Reports in Dermatological Medicine 3Figure 8: Right side after hair transplant.Figure 9: Right side with hair reflected.Patient was satisfied with results and did not require anyfurther treatment.Review of the literature shows, including our case, thathair restoration surgery using follicular unit transplantationis an eﬀective and successful treatmentmodality for temporaltriangular alopecia. In our case report, there was, as well, aconsistent result over a six-year followup. We recommendthat hair restoration surgery should be oﬀered as a first-linetreatment option for this particular type of alopecia.References[1] M. Yamazaki, R. Irisawa, and R.
