During the pregnancy, widening in diameters and structure changes of nevi may be seen especially on the front of the body. We also think that these findings might be connected with expansion of the skin during pregnancy. Dermoscopic controls are the first choice of method to analyse the nevi since the patient may not recognize these changes.

All of the CKs detected in amyloid deposits were basic type (type II). It seems plausible either that acidic CKs might be degraded faster than basic types in amyloidogenesis or that paraffin-embedded tissue specimens are less sensitive than frozen tissue sections. The results of our study suggest that when paraffin-embedded specimens are investigated by immunohistochemical methods, CK5 antibody is useful in the diagnosis of LA and MA.

A 30-year-old man presented with numerous papules, nodules and inflamed cysts. The lesions were located all over the body, including the scalp, except the palms and soles. His mother and one sister had had similar but less extensive lesions. Histopathology of the biopsy specimens obtained from the anterior chest wall, axillae and the back region was consistent with steatocystoma multiplex (SM). A diagnosis of steatocystoma multiplex suppurativum was made. The inflamed lesions were treated with oral isotretinoin (1 mg/kg per daily) for 6 months. At the same time, cryotherapy was used for non-suppurating lesions smaller than 2 cm. When the patient was evaluated 6 months later, cosmetic results were good. No new lesions have appeared in the subsequent 12-month follow up.

Melkersson-Rosenthal (MRS) syndrome is characterized by a classical triad of recurrent or persistent orofacial swelling, peripheral facial nerve paralysis and lingua plicata. Granulomatous cheilitis (GC) is regarded as a monosymptomatic form of MRS. The exact aetiologies of MRS and GC are unknown. In this study we investigated the possible role of mycobacteria in these two conditions. A ribosomal RNA amplification-based Gen-Probe amplified Mycobacterium tuberculosis direct test was used to investigate the presence of M. tuberculosis complex in paraffin-embedded skin biopsy specimens from five patients with MRS and one patient with GC. Three of the six specimens were shown to be positive using this system; one of the positive specimens also showed positive Ziehl-Neelsen staining. These results suggest a possible mycobacterial aetiology for MRS and GC.

Significantly altered levels of HSP proteins were found in cutaneous LP lesions in comparison with normal skin and psoriasis, suggesting the role of HSPs in the pathogenesis of LP.
