Sir,

Extranodal NK-T-Cell lymphoma, nasal-type (ENKTCL-NT) is an aggressive lymphoma characterized by angiocentric and angiodestructive infiltrates of EBV positive malignant cells with an NK-cell or cytotoxic T-cell phenotype involvement.[1] The infiltrate involves tissues of the nasal cavity and may be seen in extranodal/extranasal sites including skin, soft tissue and gastrointestinal tract.[1]

A 73-year-old woman was referred to our dermatology department with erythematous patches on her whole body that appeared two months ago [Figure 1]a. We performed a punch biopsy of the trunk lesion for a differential diagnosis. Histopathologically, vacuolar degeneration of the basal layer and interface dermatitis with eosinophils were observed [Figure 1]b. We suspected erythema multiforme and treated the patient with systemic corticosteroids. Her skin lesions improved slightly. Systemic corticosteroids cannot be tapered because of the relapsing skin lesions. After 8 weeks, she complained of oral and nasal erosion, and a new bulla appeared on her arm [Figure 1]e. A biopsy of bulla with a direct immunofluorescence test was performed. Necrotic epidermis with lymphoid cell infiltration was observed, but the direct immunofluorescence test was negative. The patient's symptoms were not well controlled, and the systemic corticosteroids dose was increased. She complained of persistent nasal discomfort and was referred to the otorhinolaryngology department. A biopsy of her nasal septum identified diffuse interstitial atypical lymphoid cells with angiocentric and angiodestructive patterns [Figure 2]a and [Figure 2]b. Immunohistochemistries of CD3, CD7, CD56, granzyme B, and EBV in situ hybridization (ISH) were positive [Figure 2]c, [Figure 2]d, [Figure 2]e, confirming ENKTCL-NT diagnosis. The initial trunk and arm biopsy slides were reviewed, showing CD56-and EBV-positive lymphoid cells [Figure 1]c, [Figure 1]d and [Figure 2]c, [Figure 2]d. Erythematous patches on the trunk and bulla were clinical manifestations of ENKTCL-NT. Eight months after the diagnosis, new hyperpigmented patches developed in her extremities [Figure 2]f. They were also confirmed as ENKTCL-NT.{Figure 1}{Figure 2}

The cutaneous ENKTCL-NT manifests in various ways. Subcutaneous nodules were most commonly observed (42%) in 24 primary cutaneous ENKTCL patients,[2] followed by cellulitis-like (33%) and erythematous to purpuric patches (25%). In 10 ENKTCL-NT patients,[3] ulcers were the most common (40%) skin manifestation, followed by cellulitis (30%), plaques and nodules (30%). Our patient's initial erythematous patches can be categorized as erythematous to purpuric patches, but bulla that occurred afterward and the subsequent hyperpigmented patches are rare skin manifestations. Hyperpigmented patches have not been reported as cutaneous involvement of ENKTCL-NT, and only two cases of bulla-type involvement have been reported.[4],[5] To date, no cases have been reported of a patient showing diverse cutaneous involvement patterns over time, such as in our case. Regarding nasal discomfort, antifungal agents were initially prescribed under suspicion of candidiasis in otorhinolaryngology department. The nasal lesion of ENKTCL-NT can be misdiagnosed as candidiasis due to systemic corticosteroids, widely used in dermatology; therefore, a biopsy must be considered. Detailed history-taking and appropriate multidisciplinary approaches are keys to the diagnosis and treatment of ENKTCL-NT. When a patient manifests with chronic and refractory cutaneous lesions and erosive nasal lesions, a biopsy must be performed.
