Proximal white subungual onychomycosis (PWSO) is a rare form of nail infection that occurs almost exclusively in immunocompromised patients. Initially, in several reports, PWSO was described in ARC and AIDS patients. Later this pattern of onychomycosis was observed in patients with renal transplants, who received immunosuppressive therapy, and recently in a woman with active systemic lupus erythematosus (SLE) treated with systemic steroid therapy. We report a case of recurrent PWSO in a woman affected by a defect of polymorphonuclear chemotaxis. The association between PWSO and a defect of neutrophil chemotaxis, not yet described in the literature, suggests a point of discussion about the role of polymorphonuclear leucocyte functions in the defense mechanisms of the host affected by dermatophytosis. In this report the close association between PWSO and an immunocompromised condition is once again described. For this reason the authors emphasize the importance of investigating the common and uncommon causes of immunodeficiency in all patients affected by PWSO.

We report the case of a Mexican lupus patient who developed proximal white subungual onychomycosis on multiple toenails. Microsporum canis was the causative agent. Both nail invasion by M. canis and proximal white subungual onychomycosis are rare conditions indicative of an underlying immunodeficiency.

Onychomycosis is the most common nail disorder in adults. Predisposing factors are immunosuppression, poor peripheral circulation, diabetes mellitus, increasing age, nail trauma, and tinea pedis. Autoimmune patients, who carry many of these predisposing factors, have never been studied. Autoimmune patients, with underlying autoimmune skin diseases; pemphigus, systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), scleroderma, dermatomyositis and cutaneous vasculitis, as well as having abnormal-appearing nail(s) with suspicion of fungal nail infection were included. Clinical information was obtained. The causative organisms were identified by potassium hydroxide preparation and cultured. Duration of onychomycosis in autoimmune patients was twice longer than in non-autoimmune patients. Of those with mycological proven onychomycosis, the autoimmune patients had significantly more affected nails (p < 0.05; chi2, two-sided) compared to the non-autoimmune patients but there was no difference in the affected fingernails or toenails and clinical type of onychomycosis. Candida spp was the most frequently found in autoimmune subjects compared to dermatophytes, Trichophyton rubrum. However, dermatophytes especially Trichophyton rubrum was the most common causative organism in non-autoimmune samples, followed by Candida spp. The causative organisms were more frequently discovered in autoimmune patients, whether by potassium hydroxide (KOH) or culture, than in non-autoimmune patients (p < 0.05; chi2, two-sided).

A 39-year-old female patient with systemic lupus erythematosus was treated with terbinafine for onychomycosis. After only 7 days of treatment with 250 mg terbinafine, a widespread severe erythematous eruption developed. The results of clinical, histological and immunofluorescent examinations confirmed the diagnosis of coexisting subacute and systemic lupus erythematosus. The patient was treated with drug withdrawal and administration of cyclosporine and methylprednisolone. One year later, mycophenolate mofetil was successfully used. Exacerbation or induction of lupus erythematosus is an extremely rare cutaneous side-effect of terbinafine. Patients with lupus erythematosus should be advised about the risk of some drugs that might exacerbate their disease.

Cutaneous lupus erythematosus can be induced or precipitated by a variety of drugs. Among the cutaneous variants of lupus, subacute cutaneous lupus erythematosus is the one most often associated with drug intake. The time lag between drug intake and skin eruption makes the clinical association less obvious, and the condition is often overlooked. We report on a 50-year-old woman with previously diagnosed systemic lupus erythematosus who had a severe cutaneous flare-up seven weeks after starting treatment with terbinafine for suspected onychomycosis.

Knowledge of the anatomy and function of the nail apparatus is essential when performing the physical examination. Inspection may reveal localized nail abnormalities that should be treated, or may provide clues to an underlying systemic disease that requires further workup. Excessive keratinaceous material under the nail bed in a distal and lateral distribution should prompt an evaluation for onychomycosis. Onychomycosis may be diagnosed through potassium hydroxide examination of scrapings. If potassium hydroxide testing is negative for the condition, a nail culture or nail plate biopsy should be performed. A proliferating, erythematous, disruptive mass in the nail bed should be carefully evaluated for underlying squamous cell carcinoma. Longitudinal melanonychia (vertical nail bands) must be differentiated from subungual melanomas, which account for 50 percent of melanomas in persons with dark skin. Dystrophic longitudinal ridges and subungual hematomas are local conditions caused by trauma. Edema and erythema of the proximal and lateral nail folds are hallmark features of acute and chronic paronychia. Clubbing may suggest an underlying disease such as cirrhosis, chronic obstructive pulmonary disease, or celiac sprue. Koilonychia (spoon nail) is commonly associated with iron deficiency anemia. Splinter hemorrhages may herald endocarditis, although other causes should be considered. Beau lines can mark the onset of a severe underlying illness, whereas Muehrcke lines are associated with hypoalbuminemia. A pincer nail deformity is inherited or acquired and can be associated with beta-blocker use, psoriasis, onychomycosis, tumors of the nail apparatus, systemic lupus erythematosus, Kawasaki disease, and malignancy.

So far in the literature there have been reported only 5 patients with a recognized and well-documented history of systemic lupus erythematosus (SLE) who developed SCLE after terbinafine introduction. Here we report two women suffering from SLE who developed SCLE after initiation of oral terbinafine for onychomycosis. Skin lesions in both of them were extensive, located on the trunk, and upper and lower extremities. No exacerbation of SLE symptoms was observed at that time. Despite severe skin lesions, patients revealed good response to topical corticosteroids within a few weeks. The systemic review of the literature and our experience on terbinafine-induced SCLE developing in patients with SLE allowed to create a description for this special subset: a) terbinafine-induced SCLE usually develop in 1-8 weeks after terbinafine introduction, b) skin lesions are usually severe, disseminated including lower extremities, c) patients present Ro/SS-A La/SS-B antibodies, but anti-histone antibodies are rarely observed, d) exacerbation of SLE symptoms is rather not observed, e) eruptions clear within 2-8 weeks, f) withdrawal of terbinafine and topical corticosteroids should be considered as a first-line therapy in these cases, g) terbinafine should be carefully used in patients suffering from SLE.

Terbinafine, a systemic antifungal commonly prescribed for onychomycosis (fungal infection involving the nails) has been reported to cause various cutaneous adverse effects. We describe an overlap syndrome between cutaneous lupus and erythaema multiforme induced by this medication with a review of other reported cases.

Trichophyton erinacei is an emerging cause of dermatophyte infections, which are frequently isolated from hedgehogs. Nail infections from T. erinacei are rarely reported. We describe the case of a 23-year-old Thai female who had a history of systemic lupus erythematosus with lupus nephritis type III and who developed widespread skin and nail infections caused by T. erinacei that were most likely transmitted from a hedgehog. Although the patient did not demonstrate a clinical improvement or mycological cure following systemic itraconazole and fluconazole treatment, she achieved clinical and mycological cures after terbinafine therapy. A drug susceptibility test should be performed in patients with T. erinacei infections to facilitate decision-making about antifungal therapy. Here, we are the first to report a case of proximal subungual onychomycosis from a T. erinacei infection.
