Alopecia is one of the most common adverse events of chemotherapy and although it is not life threatening it can be psychologically devastating. In an effort to reduce chemotherapy-induced hair loss various preventive measurements, such as the scalp cooling technique, tourniquet and medications, have been developed since 1970 [1]. Methods that have been applied in order to induce scalp hypother...

Background: Scalp psoriatic itch is a prevalent yet understudied condition with numerous associated treatment challenges. Objective: The current study aims to enhance our understanding of scalp pathophysiology in order guide management and identify novel targets. Methods: Immunohistochemical analysis known neuroimmune mediators pruritus was conducted using biopsies from 27 patients psoriasis. P...

A patient with multiple erythematous nodules on her posterior scalp presented to our dermatology clinic. Biopsy confirmed the diagnosis of angiolymphoid hyperplasia with eosinophilia. The etiology of this disorder is unclear. Several cases have been treated in the past with complete surgical excision, although the recurrence rate remains relatively high.

Bacteria genetically related to Coxiella burnetii have been found in ticks. Using molecular techniques, we detected Coxiella-like bacteria, here named Candidatus Coxiella massiliensis, in skin biopsy samples and ticks removed from patients with an eschar. This organism may be a common agent of scalp eschar and neck lymphadenopathy after tick bite.

Dihydrotestosterone(DHT) has played the pathogenic role in androgenetic alopecia. Patients with genetic deficiency of 5 alpha-reductase type II enzyme, which converts testosterone to DHT, do not have androgenic alopecia. The conversion of testosterone to DHT at hair follicles leads to miniaturization. In scalp biopsy, the tissue DHT level is significantly increased in balded area than non-balde...

Tinea capitis is a common fungal infection in children but rare among neonates. We present a case of a 3-week-old infant with multiple scalp lesions for 1 week. A diagnosis of tinea capitis due to Microsporum canis was made based on clinical morphology, Wood's lamp, and biopsy with a positive PAS stain. She was effectively treated with oral griseofulvin and ketoconazole shampoo.

Cutaneous angiosarcoma is a very rare but aggressive tumor. Angiosarcoma of the scalp is very rare, and a review of the world literature revealed less than 60 cases. Here, the author reports a case of poorly differentiated angiosarcoma of the scalp. The pathological diagnosis was very difficult. A 70-year-old Japanase man was admitted to our hospital complaining of red mass of the scalp. An exc...

background: members of the malassezia genus are often lipophilic, observed as budding yeasts and found as commensals in the skin of humans. this genus opportunistically reside in several areas including scalp where under the influence of particular predisposing factors, their proliferation is increased (e.g., high activation of sebaceous glands), and leads to dandruff and seborrheic dermatitis,...

BACKGROUND Dermatofibrosarcoma protuberans is a rare tumor, representing about 0.1% of skin malignant tumors. It is characterized by local aggressiveness with significant potential for recurrence. Although metastasis is rare, it does occur. We report a case of a Burkinabe woman with dermatofibrosarcoma protuberans. CASE PRESENTATION A 27-year-old Burkinabe woman consulted our institution for ...

Castleman's disease (CD) is an uncommon B-cell lymphoproliferative disorder characterized by lymph node hyperplasia with vascular proliferation. Cutaneous involvement in CD is rare. A 65-year-old man presented with a 7-year history of gradually developing multiple reddish to violaceous indurated plaques on the scalp, trunk, and legs. On physical examination, there were palpable enlarged cervica...
