    Development of histologic features of scleroderma in congenital lesions (2002)
    Oxford, UK : Munksgaard International Publishers

    Notes: Background:  Localized scleroderma has been reported after radiation therapy, but has never been reported to occur at the site of a congenital lesion.Case report: We present two patients, both with family histories of autoimmune disease, who reported unilateral hypopigmented areas on the trunk since birth. The areas remained asymptomatic and grew with the patients until adulthood when the areas became indurated then firm and showed hyperpigmentation.Histology: Histologically, both lesions showed features of localized scleroderma with diffuse sclerosis of collagen and loss of periadnexal fat. There was a perivascular lymphoplasmocytic infiltrate with occasional eosinophils extending into the subcutaneous fat predominantly along fat septae, and diffuse loss of CD34+ stromal cell populations within the lesions.Conclusion: We propose that somatic mutations affecting vessels may predispose to increased endothelial cell apoptosis. This could lead to the development of an autoimmune response in some individuals, and the areas of localized scleroderma may be markers of susceptibility to autoimmune disease.

    CD34-positive cellular blue nevi (2001)
    Copenhagen : Munksgaard International Publishers
    Journal of cutaneous pathology 28 (2001), S. 0 
    Details
    ISSN: 1600-0560

    Topics: Medicine
    Notes: Background: Although cellular blue nevi (CBN) are well known and characterized, the histopathologic and clinical spectrum of these tumors continues to evolve. We report four CBN with a distinctive histologic and immunohistochemical pattern.Methods: The histologic features and immunohistochemical staining for S-100 protein, HMB-45, Bcl-2 and CD34 of four CBN with distinctive features were evaluated using routine methods and compared to common CBN.Results: All four of these distinctive CBN where known to be congenital, and all showed aggregates of plump spindled cells with round to oval nuclei in aggregates and more slender spindled cells with thin wavy nuclei. The slender, spindled cells showed an infiltrative pattern laterally into the dermis and deep into the subcutaneous fat. All four tumors showed diffuse expression of an immunohistochemical stain for CD34, as well as for S-100 protein, Bcl-2, and HMB-45.Conclusion: Positive immunohistochemical staining with the progenitor marker CD34 defines a subset of CBN. These tumors appear to fit within the spectrum of neurocristic cutaneous hamartomas and may arise from more primitive neurocristically derived cells. Further follow-up of these tumors will be necessary to determine whether this subset of CBN defines a subset with a characteristic biologic behavior.

    Mucoepidermoid carcinoma arising within nevus sebaceus of Jadassohn (2003)

    Notes: Background:  Nevus sebaceus (NS) of Jadassohn is a common congenital lesion associated with numerous benign and malignant tumors. However, mucoepidermoid carcinoma (MEC) has not been described in association with NS.Methods:  We describe an unusual case of MEC arising within NS.Results:  A 72-year-old man presented with an enlarging plaque on his forehead, along the hairline. Physical examination revealed a mounded, erythematous lesion that was completely excised. Histological evaluation revealed a typical MEC with areas of squamous and adenomatous differentiation with foci of typical intermediate cells.Conclusion:  The diagnosis of MEC is an important one, because it portends a poor prognosis, requiring long follow-up. This is, to our knowledge, the first report of MEC arising within NS.

    Cutaneous epithelioid schwannomas: a rare variant of a benign peripheral nerve sheath tumor (1998)

    Notes: Although benign epithelioid peripheral nerve sheath tumors have been described, they are rare, and benign epithelioid schwannomas have not yet been established as a specific histologic variant.We present four cases of tumors which we believe would meet criteria to be classified as benign epithelioid schwannomas. Biopsy specimens obtained from four different patients were examined with routine and immunohistochemical staining. All the tumors were well-circumscribed lesions that were surrounded by a capsule containing EMA-positive cells. The cellular component was composed of epithelioid cells, in which there was a lack of mitotic activity. Immunohistochemical studies showed the tumor cells were S-100 protein and Leu 7 positive and HMB-45 negative. In addition, type IV collagen encircled individual cells within the tumor, indicating a continuous basal lamina. We report a group of cutaneous epithelioid schwannomas. Although the presence of such tumors is not unexpected, this diagnosis may not be initially considered because of this rare cytoiogic feature.

    An unusual dematiaceous fungal infection of the skin caused by Fonsecaea pedrosoi: a case report and review of the literature (2003)

    Notes: Background:  A case of an unusual dematiaceous fungal infection of the skin in a 43-year-old man with diabetes mellitus treated with steroids for reactive airway disease is presented. He developed chromoblastomycosis in the left wrist and was treated with antifungals and multiple surgical excisions.Results:  Histologic examination of the excised tissue revealed widespread suppurative granulomatous inflammation in the dermis and subcutaneous tissue. Thick-walled internally septated brown fungal cells were found both inside multinucleated giant cells and extracellularly. Non-to-lightly pigmented septate hyphal elements, however, were also identified with special stains and, in retrospect, on one of the routinely stained sections. In culture, the organism was reported to initially grow as soft white colonies that soon turned to black and velvety.Conclusions:  The two unusual features of this case include the controversial report of the organism's initial growth in culture as soft white colonies and the presence of hyphal elements in addition to the sclerotic bodies in the dermis and subcutaneous tissue. This has not been reported before in human cases of dermal infection by Fonsecaea pedrosoi.

    Ossifying fibromyxoid tumor of soft parts: a case report and review (1996)

    Notes: Ossifying fibromyxoid tumor of soft parts is a recently described, rare but morphologically distinctive tumor of soft tissue, including subcutaneous soft tissue. We report a case of ossifying fibromyxoid tumor of soft parts which occurred in the subcutaneous tissue of a 68-year-olcl male, and review the clinical, histologic, and immunohistologic features of this tumor. Ossifying fibromyxoid tumor of soft parts tends to occur in the subcutaneous tissue and have been reported from the head and neck, upper and lower extremities, and trunk. Immunohistologic studies have supported a neural origin. While considered benign, local recurrence after excision is common and these tumors should be excised with clear margins to prevent recurrence.
