Medial Nail Fold

Antonella Tosti, Robert Baran, Rodney PR Dawber, Eckart Haneke Longitudinal lines Herringbone nails Transverse lines Pitting and rippling Trachyonychia (rough nails) Onychoschizia (lamellar splitting) Further reading Longitudinal lines, or striations, may appear as indented grooves or projecting ridges (Figures 3.1-3.16). Longitudinal grooves represent long-lasting abnormalities and can develop under the following conditions A Single longitudinal nail fissure is most likely due to minor trauma...

Onychomycosis and its treatment

Purulent Drainage

Antonella Tosti, Robert Baran, Rodney PR Dawber, Eckart Haneke Candida onychomycosis Further reading Fungi may invade the nails in four different ways, leading to four separate types of onychomycosis with specific clinical features, prognosis and response to treatment. The type of nail invasion depends on the fungus responsible and the host susceptibility. Invasion occurs 1 Via the distal subungual area and the lateral nail groove, leading to distal lateral subungual onychomycosis (Figure 8.1)....

Acquired longitudinal melanonychia after puberty in a whiteskinned individual requires urgent biopsy

Resultados Papanicolau

Approximately 2-3 of melanomas in whites, and 15-20 in blacks are located in the nail unit. However, malignant melanoma is rare in black people thus the number of nail melanomas does not significantly differ between these population groups. Most white patients have a fair complexion, light hair, and blue or hazel eyes. There is no sex predominance, although some reports show variable female or male predominance. The mean age at onset is 55-60 years. Most tumours are found in the thumbs or great...

Periungual and subungual warts

Recalcitrant Wart

Common warts are caused by human papillo-maviruses of different biological types (Figures 5.16-5.18). They are benign, weakly infective, fibre-epithelial tumours with a rough keratotic surface. Usually periungual warts are asymptomatic, although fissuring may cause pain. Subungual warts initially affect the hyponychium, growing slowly toward the nail bed and finally elevating the nail plate. Bone erosion from verruca vulgaris occasionally occurs although some of these cases may have been...

Alteration to surrounding tissue

Pincer Toenail Home Treatment

Tennis (or sportman's) toe is a brown-black discoloration due to subungual haemorrhage caused by special stresses on the longest toe (great toe and or the second toe). Pain is associated with the appearance of the damage. In tennis, this occurs because the player frequently stops abruptly the forward motion of the body propels the toes into the toe box and tip of the footwear. Hard playing surfaces contribute to the injury. In distinction to tennis toe, jogger's toe tends to involve the third,...

Blistering distal dactylitis

Dactylitis

Blistering distal dactylitis is a variant of streptococcal skin infection. It presents as a superficial, tender, blistering beta-haemolytic streptococcal infection over the anterior fat pad of the distal phalanx of the finger (Figure 5.40). The lesion may or may not have a paronychial extension. This blister, containing thin, white pus, has a predilection for the tip of the digit and extends to the subungual area of the free edge of the nail plate. The area may provide a nidus for the...

Retracting Nail Fold

Clinically, the proximal and lateral nail folds show erythema and swelling. The cuticle is lost and the ventral portion of the proximal nail fold becomes separated from the nail plate. This newly formed space has an important additional role in maintaining and aggravating chronic paronychia it becomes a receptacle for microorganisms and environmental particles that potentiate the chronic inflammation. With time the nail fold retracts and becomes thickened and rounded. The course of...
