Table 1 Diagnosis and associated OCT features Patient/Diagnosis (biopsy verified)

OCT features

1/Tumour stage MF

Homogenous wavy-shaped formation of the superficial skin. The fringe is clearly delineated by a hyperreflective border

2/Tumour stage MF

A sharply demarcated hyperreflective formation extending from epidermis to the deeper part of the dermis

3/Plaque stage MF

Normal architecture of the skin disrupted. Not possible to identify the dermo-epidermal junction (DEJ). Hyperreflective homogenous appearance of the dermis. Normal vessels not visible

4/Lymphomatoid papulosis

Clear delineation between papule, normal epidermis and dermis. The border is a thickened hyperreflective band

5/Lymphomatoid papulosis

Delineation between papule and normal epidermis and dermis is evident. The border is a thickened hyperreflective band. Normal vessels not visible in the lesion

group.8 The study depicted a patch stage MF with a striking elongated dark dermal structure. Although the findings differ significantly from our results the elongated structure may represent splitting of the dermal layer. OCT appears to identify a striking morphology in some CTCL lesions not seen in other skin tumours 4,9 thus indicating conventional OCT as a potential tool for non-invasive studies of cutaneous lymphomas. However, discrimination between superficial inflammatory skin diseases and early MF stages may potentially constitute a diagnostic challenge.10 Although there is a lack of OCT studies evaluating different CTCL’s at baseline we speculate that OCT imaging offers utility in quantifying and monitoring epidermal and dermal responses to treatment without relying on an array of biopsies. Additional studies including more patients and various cutaneous lymphomas are warranted to identify the diagnostic accuracy of our findings.

IgG/IgA pemphigus representing pemphigus vegetans caused by low titres of IgG and IgA antibodies to desmoglein 3 and IgA antibodies to desmocollin 3 Editor A 50-year-old Japanese man presented with 3-week history of erosive pustules with pruritus on the left foot in February 2013. The patient suffered from Eisenmenger’s syndrome. The patient was administered with valacyclovir for tentative diagnosis of herpes simplex at a local clinic for 2 weeks. However, because the skin lesions were intractable, the patient was referred to us and was admitted to our hospital for a more extensive examination.

Figure 1 Clinical features on admission. (a) Skin lesion on the left foot. (b) Verrucous lesion on the oral mucosa.

On admission, the pustules and erosions spread to the plantar and dorsal regions of the left foot (Fig. 1a). He also presented with oral verrucous plaques (Fig. 1b). Laboratory findings (normal values are in square brackets) showed a normal white blood cell count (7.8 9 103/lL, [4.0–8.5 9 103]) with lymphopenia (13%, [27–46%]) and eosinophilia (17%, [1–6%]) as well as elevated C-reactive protein (1.46 mg/dL [
