Background: In order to assess the short term risks of pneumonectomy for lung cancer in contemporary practice a one year prospective observational study of pneumonectomy outcome was made. Current UK practice for pneumonectomy was observed to note patient and treatment factors associated with major complications.

A 79-year-old man presented with a pigmented nodule on the right ear which, on epiluminescence microscopy, demonstrated a diffuse grey-blue colour. Skin biopsy revealed an irregularly acanthotic epidermis with lobular clusters of atypical keratinocytes that projected into the dermis in the pattern of an invasive squamous cell carcinoma. Numerous dendritic melanocytes were present throughout the lesion. Although the close relationship between the highly dendritic intra-epidermal melanocytes and the atypical keratinocytes raised the issue of whether this tumour represented a malignant melanoacanthoma, the authors considered the lesion to be better classified as an unusual variant of pigmented squamous cell carcinoma.

13-year-old girl presented with a 10-year history of multiple discrete red firm papules situated on her right upper arm. The histopathology examination revealed a massive subepidermal lymphohistiocytic infiltrate, consistent with acral pseudolymphomatous angiokeratoma of children. Treatment with topical application of mometasone furoate 0.1% cream once daily for 6 months improved the lesions partially. However, these papules returned to their pretreatment appearance and consistency within 6 months after the cessation of the topical corticosteroid. The authors prefer the term 'papular angiolymphoid hyperplasia' for this entity, based on the absence of histological angiokeratomatous features, the benign nature of the lesion and the previously reported cases from adults and non-acral sites.
