Scalp necrosis secondary to giant-cell arteritis

Recipient site scalp necrosis: A rare postoperative complication of hair transplantation

BACKGROUND

Recipient area scalp necrosis is considered a potential complication of hair transplantation, but has rarely been reported. A small number of patients have developed scalp necrosis after hair transplantation with the widely used Follicular unit excision (FUE) technique. There are no guidelines to prevent and manage this complication. The aim of this study was to provide an insight into the pathogenesis, prevention, and management of scalp necrosis following hair transplantation.

METHODS

From 2012 to 2021, among more than 10 000 patients who underwent hair transplantation, only three developed scalp necrosis in our clinical experience, besides, one patient transferred to our hospital because of scalp necrosis after undergoing hair transplantation. According to the disease etiology and patients' symptom, a combination of wound management and antimicrobial therapy was employed. This study was approved by the institutional ethics committee of Nanfang Hospital.

RESULTS

Of the four patients, three received timely treatment and had a good prognosis. Necrosis became confined and healed within 2-3 weeks. Grafts in the lesion area partially survived. In case 4, due to improper treatment at the early stage, the lesion developed extensively and deeply, which not only delayed wound healing, but also resulted in complete loss of grafts.

CONCLUSION

Preoperative prophylaxis, timely diagnosis, and immediate treatment of scalp necrosis can prevent serious complications and reduce morbidity after hair transplantation.

Bitemporal scalp, lip and tongue necrosis in giant cell arteritis: a rare presentation

A 74-year-old man was presented with fever, bilateral throbbing temporoparietal headache, jaw claudication, and bilateral loss of vision. On examination, he had bilateral scalp necrosis with impending necrosis of lip and tongue. Temporal artery biopsy was done, and it was compatible with active temporal arteritis. This is one of the rare presentations of giant cell arteritis where there is simultaneous necrosis of scalp, lip, and tongue, and to the best of our knowledge, it is the first case reported from India.

Scalp necrosis as a late sign of giant-cell arteritis

Retinal infarction and scalp necrosis are described as unusual but devastating complications of giant-cell arteritis. We report a patient with this rare complication and emphasize the importance of timely diagnosis and treatment of giant-cell arteritis.
