Perianal basal cell carcinoma (BCC) is a rare tumour and only a few case reports can be found in the literature. In this location, it is important to differentiate a BCC from a basaloid cloacogenic carcinoma, as the first is an invasive but localized tumour, while the second has a high capacity for metastasis.

Periarticular fibrous nodules have been described in patients with late-phase acrodermatitis chronica atrophicans (ACA) in the setting of Lyme borreliosis. We report the clinical and histopathological study of two patients with periarticular fibrous nodules and with Lyme borreliosis and discuss the relationship between these nodules and ACA.

Three patients with vegetating iododerma as a result of potassium iodide therapy are presented. The first patient had polyarteritis nodosa, the second had monoclonal gammopathy of undertermined significance, and the third had multiple myeloma. Vegetating iododerma probably represents an idiosyncratic response to iodides; patients with polyarteritis nodosa and paraproteinemias may be predisposed.
A patient with mycosis fungoides developed a nephrotic syndrome. Renal biopsy revealed deposits of a highly organized fibrillar material which did not stain with the typical amyloid stains; this picture was consistent with the diagnosis of non-amyloidotic fibrillary glomerulopathy or immunotactoid glomerulopathy. We believe this is the first case reported of immunotactoid glomerulopathy associated with mycosis fungoides. Possible pathogenetic implications are discussed with reference to previous publications.

We report herein a new case of dyshidrosiform pemphigoid. Although vesiculo-bullae on palms or soles are frequent components of bullous pemphigoid, they are rare as a presenting phenomenon. In our opinion, dyshidrosiform pemphigoid should not be regarded as a distinctive form of localized pemphigoid.
A case of epidermolysis bullosa acquisita (EBA) with negative direct immunofluorescence and multiple myeloma is reported. Epidermolysis bullosa acquisita has been associated with several systemic diseases, but only three cases diagnosed of EBA have been associated with multiple myeloma in the literature.
