This consistency explains the anatomical basis for the realization of composite-free tissue transfer in cases of banked fingers. The osteotomies could be performed at well-defined distances from the joints.

It is well known that a cutaneous artery is constantly located near a cutaneous peripheral nerve, forming a vascular plexus around it. This vascular axis can be either a true artery or an interlacing network, ensuring the vascularization of the nerve and giving off several neurocutaneous perforators to the skin. The anatomy of the accompanying arteries of the dorsal branch of the ulnar nerve (DBUN) and their relationships with the dorsal branch of the ulnar artery (DBUA) were investigated in 22 fresh upper limbs injected with colored neoprene latex. A constant perineural vascularization of the terminal branch of the DBUN was observed in the fourth web space, connected distally with the corresponding dorsal metacarpal or palmar digital arteries. Our findings therefore provide anatomical bases for a new neurocutaneous island flap. Moreover, they allow us to describe a precise surgical technique in order to raise this flap over the larger branch of the DBUN, in the fourth intermetacarpal space. The flap is harvested on the medial aspect of the dorsum of the hand, and its point of rotation is located in the fourth web space, 1 cm proximal to the metacarpophalangeal joint. It is supplied by a reversed flow originating from distal anastomoses of the perineural vessel with the dorsal metacarpal and digital palmar arteries in the fourth web space. This flap does not involve in its pedicle the distal course of the DBUA. It represents a pure neurocutaneous flap.

Cutaneous melanoma is a public health issue and the head and neck region is of particular interest, despite accounting for only 9.0% of the total body surface, it harbours 20% of melanoma cases. Data from the literature show that scalp melanomas (SM) carry high mortality rates, with a 10-year survival rate of 60% which lead them to be named as the "invisible killer". Moreover, SMs are more common in the elderly than in young population, and they occur six times more frequently in men than in women. This is probably related to the higher incidence of androgenetic alopecia and a higher cumulative and intermittent ultraviolet damage on the scalp. Histologically, SM is a heterogenous group, including lentiginous melanoma (LM), desmoplastic melanoma, superficial spreading and nodular melanoma. Thin melanomas tend to display an atypical network or pseudo-network and regression in dermoscopy. Blue-white veil, irregular pigmented blotches and an unspecific pattern are most commonly detected in thick lesions. On reflectance confocal microscopy (RCM), the most frequent pattern is irregular meshwork, but also ringed and disarranged pattern have been described. Differential diagnosis includes benign solar lentigo, actinic keratoses, lichen planus like keratosis, melanocytic nevi and blue nevi. All suspicious lesions should be biopsied; therefore, an excisional biopsy with 2 mm margins is usually the best option. The management of SM is the same as for melanoma on other body sites. However, sentinel node biopsy tends to be more challenging, as well as achieving adequate excision margins of the primary tumor. In this review, we summarize clinical, pathologic, dermoscopic and RCM features of SM, and focus on its epidemiology, risk factors and best management options.

Secukinumab-induced paradoxical hidradenitis suppurativa successfully treated with adalimumabDear Editor, A 47-year-old woman presented with a 16-year history of psoriasis (PsO) and recent onset of psoriatic arthritis (PsA).Prior treatments included topical vitamin D analogs, topical and oral corticosteroids, and oral cyclosporine, with the patient experiencing unsatisfactory disease control. At our observation, the patient presented a plaque type PsO (Psoriasis Area Severity Index [PASI] score: 10.5) with sharply demarcated erythematous plaques of the scalp, back, and inframammary areas, and related severe joint symptoms at proximal interphalangeal and metatarsophalangeal joints (subjective pain Visual Analog Scale [pain-VAS] of 80 and Disease Activity Score 28CRP4 [DAS28-CRP4] of 4.89).
