Vulvar melanoma: a report of 20 cases and review of the literature

BACKGROUND: Vulvar melanoma is the second most common vulvar malignancy and represents a significant women's health issue. OBJECTIVE: To report experience with 21 cases of vulvar melanoma in 20 patients and to review the literature about the condition. METHODS: Parameters retrospectively reviewed included age at diagnosis, family history of melanoma, location on the vulva, atypical nevi, Breslow depth, ulceration status, histologic pattern, presenting signs and symptoms, and the results of sentinel lymph node biopsy. Molecular characterization of the melanocortin type 1 receptor was performed in 1 patient. RESULTS: A family history of cutaneous melanoma was present in 15% of cases. The mean Breslow depth was 2.8 mm (range, 0.0-11.0 mm). Ten patients successfully underwent sentinel lymph node biopsy, results of which were positive in 2 (20%). Reported for the first time is that one patient had a germline mutation in the melanocortin type 1 receptor. CONCLUSION: Vulvar and cutaneous melanoma behave similarly despite their unique pathogeneses. Sentinel lymph node biopsy can be performed successfully for vulvar melanoma.     

Pulmonary carcinoid associated with melanoma: two cases and a review of the literature

To our knowledge, this is the first report in the British literature documenting the co-occurrence of melanoma and pulmonary carcinoid. The only other report is from America and documents pulmonary carcinoid in association with a parathyroid hormone-producing melanoma. We report two patients with melanoma who presented with nodules on chest X-ray. Both underwent resection of assumed lung metastasis which unexpectedly revealed primary pulmonary carcinoid. Evidence of an association between these two tumours which show striking biological and pathological similarities is discussed. The incidence of pulmonary carcinoid is increasing and with the improved power of radiological assessment we may see additional accounts of such an association in the near future.     

Lupus erythematosus associated with erythema multiforme: report of two cases and review of the literature

Rowell's syndrome (RS) is a rare presentation of lupus erythematosus (LE) with erythema multiforme‐like lesions associated with antinuclear, anti‐La (SS‐B)/anti‐Ro (SS‐A) antibodies and rheumatoid factor (RF) positivity. This syndrome is suggested to be a different variant of cutaneous lupus erythematosus by some authors in literature. Here we present a 64‐year‐old woman with LE and a 51‐year‐old woman with LE and Sjögren syndrome (SS) who had erythema multiforme‐like eruptions and discuss the coexistence of lupus erythematosus and erythema multiforme.     

Desmoplastic malignant melanoma of the lip: a report of 6 cases and review of the literature

Desmoplastic malignant melanoma is a rare neoplasm consisting primarily of spindle-shaped melanoma cells embedded in a fibrous stroma, with approximately 6% of cases occurring in the lip. A literature search revealed that most reported cases occur in sun-exposed areas in older men. Few cases of desmoplastic malignant melanoma of the lip in young people (in their mid-twenties) have been described. We report 6 previously undocumented cases of labial desmoplastic malignant melanoma occurring in young individuals and review 20 cases from the literature. Physicians should consider the possibility of desmoplastic malignant melanoma in young people who present with atypical lip lesions, which on histopathologic analysis demonstrate spindle-cell hyperplasia. Although this diagnosis is rare and there have not been reports of such patients in the literature thus far, our findings should alert clinicians to the possibility of desmoplastic malignant melanoma as a diagnosis for lip lesions in young people.

Atypical fibroxanthoma-like amelanotic malignant melanoma: A case report and literature review

Atypical fibroxanthoma (AFX)-like malignant melanoma is very rare. Here, we report a case of amelanotic AFX-like melanoma in a 72-year-old Taiwanese woman presenting with two separate, asymptomatic, enlarging erythematous nodules within a large hypopigmented patch on her left cheek. Histologically, both lesions showed cellular nodules in the reticular dermis separated from the overlying flattened epidermis by a zone of solar elastosis or fibrosis. The tumor consisted of sheets of atypical epithelioid cells arranged in a vague nesting pattern, as well as many atypical large or gigantic cells with one or more, large hyperchromatic, vesicular, or pleomorphic nuclei with prominent nucleoli, and moderate-to-abundant eosinophilic or foamy cytoplasm. Focal intraepidermal proliferation of atypical melanocytes with a pagetoid pattern was found only in the periphery of the main tumor. The tumor cells were moderately to strongly positive for S-100, Melan-A, and HMB-45. The pleomorphic giant cells were focally CD68-positive but CD163-negative. The patient underwent tumor excision followed by radiotherapy due to the narrow surgical margins. A sentinel lymph node biopsy revealed no metastasis of the melanoma. This case illustrates the importance of scrutinizing any subtle proliferation of atypical melanocytes in the epidermis in an AFX-like tumor in order to avoid misdiagnosis.     

Dermatomyositis associated with malignant melanoma-case report and review of the literature

Dermatomyositis (DM) is a connective tissue disorder characterized by cutaneous and muscle involvement. It is a well recognized paraneoplastic syndrome and has been linked with malignancy in 15–34% of adult patients.^1,2 The course of DM in such patients usually correlates closely with the activity of the underlying malignancy.³ We report a patient who developed DM 4 years after excision of a malignant melanoma (MM) from the back and 1 year before the diagnosis of metastatic disease. A literature review revealed that the association of dermatomyositis with MM is rare and consistent with a dismal prognosis.     

Combined high-grade basal cell carcinoma and malignant melanoma of the skin ("malignant basomelanocytic tumor"): report of two cases and review of the literature

We describe two cases of a malignant cutaneous neoplasm with combined phenotypical features of high-grade basal cell carcinoma and malignant melanoma. Some tumor cells showed a keratinocytic phenotype (cytokeratins, p63) and others a melanocytic phenotype (HMB-45, MART-1, Melan-A, S100-protein). We favor the hypothesis of a tumor with bidirectional keratinocytic and melanocytic differentiation, an exceptionally rare event.     

Lichen myxoedematosus associated with human immunodeficiency virus infection – report of two cases and review of the literature

Lichen myxoedematosus (LM), or papular mucinosis, is an uncommon papular eruption caused by the dermal deposition of mucin. Three clinical forms can be distinguished, namely localised, disseminated (involving more than one site), and generalised LM, the last is called scleromyxoedema, and demonstrates erythema and skin sclerosis.¹ Paraproteinaemia, often consisting of an abnormal IgG with lambda light chains, is usually present in patients with LM.² Visceral involvement has also been documented.³ An association between LM and human immunodeficiency virus (HIV) infection has been reported recently. We now describe two further HIV-positive patients with LM and present a review of the literature regarding this association.     

Malignant melanoma arising in a radiotherapy field: report of two cases and review of the literature

We report 2 patients who developed melanoma or melanoma metastases in radiation fields 6 and 43 years after radiation therapy, respectively. One of the patients had received adjuvant hyperfractionated photon therapy for Ewing sarcoma, while the other patient had received X-ray therapy for a hemangioma. While postradiation secondary cancers with a long latency period are not uncommon, the development of melanoma is exceedingly rare.

Desmoplastic melanoma associated with an intraepidermal lentiginous lesion: case report and literature review

Desmoplastic melanoma tends to present as firm, amelanotic papules. Microscopically, it reveals a proliferation of fusiform cells in the dermis and variable collagen deposition, as well as intraepidermal melanocytic proliferation of lentiginous type in most cases. Biopsy in a 61-year-old white male patient, who had received a diagnosis of lentigo maligna on his face 10 years before, revealed a proliferation of dermal pigmented spindle cells and collagen deposition, reaching the deep reticular dermis, with a lentiginous component. Immunohistochemistry with S-100, Melan-A and WT1 showed positivity, but it was weak with HMB45. Desmoplastic melanoma associated with lentigo maligna was diagnosed. Several authors discuss whether desmoplastic melanoma represents a progression from the lentiginous component or arises "de novo". Desmoplastic melanoma represents a minority of cases of primary cutaneous melanoma (less than 4%). Identification of lentigo maligna indicates that desmoplastic melanoma should be carefully investigated.     

Eosinophilic pustular folliculitis associated with hematological disorders: A report of two cases and review of Japanese literature

Eosinophilic pustular folliculitis (EPF) occurs in patients with hematological disorders. However, clinical information about hematological disorder‐associated EPF is scarce. We report two cases of EPF associated with mantle cell lymphoma and reviewed the available published work on Japanese cases. We identified a total of 23 Japanese cases, including the two cases reported here, who had hematological disorder‐associated EPF. Fourteen cases were associated with treatment for hematological malignancies (transplantation‐related EPF) and nine cases were associated with hematological malignancies themselves (hematological malignancy‐related EPF). Although the skin eruption was clinically indistinguishable between the two subtypes, transplantation‐related EPF occurred on the face and trunk of young and middle‐aged men and women, whereas hematological malignancy‐related EPF occurred mostly on the face of older men. Peripheral blood eosinophilia was more frequently observed in transplantation‐related EPF. These observations suggest variations among patients with EPF associated with hematological disorders.

Olmsted syndrome: report of two new cases and literature review

Olmsted syndrome is a rare keratinization disorder; 18 cases have been published so far. It associates a mutilating cogenital palmoplantar keratoderma with periorificial erythematokeratotic lesions. We report herein two new unrelated male children with Olmsted syndrome (OS), one of whom was studied by light and electron microscopy. Our histological, immunohistochemical, and ultrastructural findings suggest that this disease is related to epidermal hyperproliferation. We present herein a review of the twenty cases published so far and discuss the major clinicopathological and genetic features of this disease.     

Trigeminal trophic syndrome: a report of two cases with review of literature

Trigeminal trophic syndrome, a rare cause of facial ulceration, is the consequence of damage to the trigeminal nerve or its central sensory connections. We report two cases of trigeminal trophic syndrome, complications of cerebral vascular accidents. A 65-year-old woman complained of numerous and progressive ulcers of the right side of her face of 2 month's duration. A 67-year-old woman presented with an ulcer of the ala nasi of 10 week's duration. This syndrome most commonly occurs in women with an average age of 57 years. About 100 cases are reported in the literature. The diagnosis is made on clinical grounds, and is suggested when loss of sensation occurs in association with unilateral facial ulceration, especially involving the ala nasi. Once the ulcers appear, they are extremely persistent.
