    Sclerosing adenosis of the prostate. Report of three cases with electronmicroscopy and immunohistochemical study (1992)

    Notes: Three cases of a rare variant of prostatic adenosis with the features of sclerosing adenosis, an uncommon lesion sometimes confused with prostatic carcinoma, are reported. The lesions consisted of a small, single nodule in prostates otherwise showing typical adenomatous and fibromuscular hyperplasia. The lesions were composed of crowded small glands, small solid nests and individual cells embedded in a cellular stroma. Immunohistochemistry showed that the glands were lined by basal cells positive for high-weight keratins (EAB-903 and AE-3), a finding which confirms the benign nature of the lesion. S-100 protein and smooth muscle actin were also positive in the same basal cells suggesting myoepithelial differentiation, a character not found in basal cells outside this lesion. This finding was confirmed at ultrastructural level by the finding of numerous thin filaments in the cytoplasm of basal cells. It is important to recognize this lesion in order to avoid confusion with well-differentiated prostatic carcinoma.

    Atypical dermal nodules in benign melanocytic naevi (1997)
    Oxford, UK : Blackwell Science Ltd
    Histopathology 31 (1997), S. 0

    Notes: Aims: The prognosis of deeply invasive melanoma can be poor and to a large extent it is unresponsive to treatment once metastases have occurred. It is therefore important that any dermal melanocytic lesions that have some features suggestive of melanoma but are nevertheless benign, should be identified. Methods and results: A series of 40 benign melanocytic naevi is described in which the clinical presenting feature was a central focus of increased pigmentation. This was found histologically to correspond to dermal nodules of large melanocytes showing some, usually mild, nuclear atypia but low indices of cellular proliferation. The nodules are found within otherwise typical melanocytic naevi. The clinical and histological differential diagnosis included invasive melanoma but in follow-up, which is admittedly short (mean 24 months), none have recurred or metastasized. Conclusions: It is suggested that the nodules represent terminal differentiation of melanocytes rather than proliferative changes. They should be distinguished from melanoma and regarded as a variant of benign melanocytic naevi.

    Notes: Aims: We describe a previously unrecognized pigmented tumour of the skin and suggest a possible relationship with the follicular bulb.Methods and results: A pigmented epithelial neoplasm clinically simulating a malignant melanoma of the skin was present in a 92-year-old woman, on her left leg. It was composed of three cell types: squamous cells with trichilemmal keratinization, basaloid cells and dendritic melanocytes. The presence of three cell types was confirmed by immunohistochemistry and electron microscopy.Conclusions: The tumour showed differentiation towards the hair follicular bulb and the descriptive term of follicular baso-squamous melanocytic tumour is suggested.

    Naevocytic naevi with vascular-like spaces (1991)
    Oxford, UK : Blackwell Publishing Ltd
    British journal of dermatology 124 (1991), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005

    Notes: Fourteen cases of naevocytic naevi with anastomising lacunae suggestive of vascular spaces are reported. The cells lining these lacunae were consistent with naevus cells, being positive for vimentin and S100 protein and negative for factor VIII-related antigen and Ulex europaeus I. The cells were not surrounded by laminin or type IV collagen. We suggest the formation of these vascular-like spaces may be due to defective production or increased degradation of components of the basement membrane with a consequent lack of cohesion.

    Notes: We describe a 69-year-old man with a non-small cell carcinoma of the lung, stage III B, who developed bilateral multiple erythematous lesions in the abdominal–inguinal area following treatment with gemcitabine. Histologically, the lesion was characterized by a heavy lymphocytic infiltrate with large CD30+ cells. The lesion was highly suggestive of cutaneous involvement by malignant lymphoma, but complete regression was observed after cessation of gemcitabine. Although rarely reported, gemcitabine therapy can induce skin lesions. Pathologists should be aware of this possibility in order to avoid a misdiagnosis.

    Atypical cutaneous mycobacteriosis diagnosed by polymerase chain reaction (2002)

    Notes: Summary Atypical mycobacteria are important human pathogens. Although they often cause systemic disease, mycobacterial infection may present solely as cutaneous lesions. It is not easy to detect nontuberculous mycobacteria by the traditional histochemical Ziehl–Neelsen stain, or by culture on specific media. Polymerase chain reaction (PCR) may be used to identify nontuberculous mycobacteria in skin lesions. We report a 40-year-old man and a 36-year-old woman, both of whom were immunocompetent and kept fish, who had skin lesions on the backs of their right hands. Ziehl–Neelsen staining and culture on Lowenstein–Jensen media were negative. Mycobacterial DNA was detected by amplification of 16S ribosomal DNA. In both cases, PCR-enzyme-linked immunosorbent assay showed a positive signal when probes for Mycobacterium (universal probe) and M. chelonae were used, and in one patient M. fortuitum was also discovered. Antibiotic therapy with clarithromycin 500 mg twice daily was begun. After 6 months of treatment, the skin lesions were cured.

    Melanocytic lesions of the palm and sole (1994)

    Notes: Pigmented lesions of palmar and plantar skin may cause diagnostic problems, partly because they are infrequently excised and also because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. We have examined a series of benign melanocytic lesions and compared them with melanomas from these sites. The presence of severe melanocytic atypia was the most valuable feature in distinguishing between naevi and melanomas. Pagetoid infiltration of the epidermis by single atypical cells, or small groups of cells with abundant pale cytoplasm was seen only in melanomas, while transepidermal elimination of well-circumscribed nests was present only in benign lesions. A lymphocytic infiltrate was present in the dermis in 13 of 14 malignant lesions, but only two of the 26 naevi showed a sparse infiltrate: we suggest that the presence of a lymphocytic infiltrate should prompt a careful search for other features of malignancy. Other features examined, including elongation of rete ridges, pattern of melanocyte distribution at the dermo-epidermal junction, dermal sclerosis, and pigment in the stratum corneum or in the dermis, were seen in both naevi and melanomas and were not found to be useful in distinguishing benign from malignant lesions.
