A 6 year prospective analysis of the diagnosis of malignant melanoma in a pigmented-lesion clinic: even the experts miss malignant melanomas, but not often.

We investigated whether the pigmented-lesion clinic (PLC) run by the Department of Plastic and Reconstructive Surgery at Frenchay Hospital was effective in making and excluding the diagnosis of malignant melanoma, by looking at the pattern of referrals over time, the number of melanomas excised and melanomas in which the diagnosis was delayed or missed. We also investigated whether the PLC was having an effect on the thicknesses of melanomas excised. All 9968 patients attending the PLC between 1 January 1993 and 31 December 1998 were included in the study and 586 malignant melanomas were diagnosed; 24.7% of excisions led to the diagnosis of malignant melanoma. Seven invasive melanomas and two lentigo malignas were missed. There was one histological false negative. The PLC has a sensitivity of 98.5% and specificity of 89.2% for the diagnosis of melanoma; the negative predictive value is 99.9%. The PLC is effective in rapidly making or excluding the diagnosis of malignant melanoma, but has had no effect on the average thickness of melanomas excised over the 6 year study period.     

Subungual Malignant Melanoma of the Hand: Unusual Clinical Presentation: Case report

A 75-year-old woman presented with a four month history of a slowly growing tumour on the distal portion of the third finger of her left hand. The lesion suggested clinically an inflammatory process or an epidermoid carcinoma. The finger was amputated through the proximal interphalangeal joint. Microscopic examination showed an acral-lentiginous melanoma, subungual type (Clark level V). No elective lymph node dissection was done, and no prophylactic chemotherapy was given. The patient remains free of disease eight months after operation. Clinicians should be aware of this rare lesion, which may mimic other benign or malignant conditions.     

Aggressive Digital Papillary Adenocarcinoma in a Young Female—a Rare Presentation

A 20 year old female presented with a recurrent soft tissue swelling over the medial aspect of proximal phalanx of left little finger. It had recurred one year after excision. There was no lymphadenopathy or bony involvement. Previous histopathology reports were not available. After excision histopathological diagnosis was aggressive digital papillary adenocarcinoma. Later Ray's amputation of little finger was planned. Aggressive digital papillary adenocarcinomas are rare sweat gland tumors which occur on hands, fingers, and toes. They have high local recurrence rate and may metastasize to lungs and lymph nodes.     

Gastrointestinal metastasis of melanoma: a case study

The Authors report on a case of multiple metastases located in the jejunum (where it caused intussusception), the omentum, and retroperitoneum having originated from a malignant melanoma with subungual primary site on first finger of left hand. After thoroughly surveying the specific literature, the Authors deal in more detail with current treatments and therapeutic prospects for this kind of neoplastic disease.     

Primitive cerebral melanoma: case report and review of the literature

BACKGROUND: Central nervous system primary malignant melanoma accounts for approximately 1% of all the cases of melanoma; reports in the literature are relatively rare. CASE DESCRIPTION: A 74-year-old man was hospitalized because of an episode of aphasia. The neuroradiologic examinations demonstrated a round homogeneous lesion extending near the left sylvian fissure. He had no extracranial abnormalities. The patient underwent a neurosurgical procedure and the tumor was macroscopically totally excised. Pathological examination of the surgical specimen revealed a histological appearance similar to that of melanoma. A diagnosis of primary CNS melanoma was made after careful dermatologic and ophthalmologic examination, which ruled out presence of cutaneous or choroidal melanoma. The patient did not receive any further treatment and he is free of disease 2 years after diagnosis. CONCLUSIONS: We report a case of primary cerebral melanoma of the left temporal lobe; clinical, neuroradiological, and histological findings are discussed with review of the literature. Primary melanoma of the CNS may present either with localized intra/extra-axial mass lesions or with meningeal spread, which carries a worse prognosis. The prognosis of cerebral primitive melanoma is variable, although it is common opinion that primitive cerebral melanoma has a better prognosis than cutaneous melanoma, with two cases in the literature surviving 9 and 12 years.     

Mucosal malignant melanoma in upper aerodigestive tract: report of two cases

Primary malignant melanoma has been seen in virtually all sites and organ systems where neural crest cells migrate. Upper aero-digestive tract is the unusual site. We presented two cases of mucosal malignant melanoma. A 59-year-old female patient had been suffering from nasal airway obstruction and headache for three months, and was admitted to our clinic. There was an upper cervical lymphadenopathy 5 cm in diameter ipsilaterally. Computerized tomography presented a nasal mass originating from the left maxillary sinus, and extending into nasal cavity and the left lateral wall of nasopharynx. Left total maxillectomy and radical neck dissection was performed. Postoperative radiotherapy was applied. A 68-year-old male patient suffering from nasal airway obstruction, hypernasality, dysphagia, and oral bleeding was admitted to our clinic. Oral examination revealed the tumoral mass protruding downward through oropharynx. The second patient referred to medical oncology. There was no recurrence in the first patient 18 months later. And the second patient died one year later. We believe that nasal mucosal malignant melanoma was rare, and carefully evaluated since it may be amelanotic lesion. Nasopharyngeal mucosal malignant melanoma is very rare, and has worse prognosis.     

Malignant melanoma in the thymus

A case of malignant melanoma in the thymus is reported. Diagnostic imaging demonstrated a left anterior mediastinal mass in a patient with giant pigmented nevus without malignant change. Histologic and cytologic specimens obtained from the tumor revealed that the tumor was malignant melanoma. Surgery revealed malignant melanoma in the left lobe of the thymus. Many cell nests of pigmented nevi were observed throughout the thymus. The malignant melanoma was thought to have originated from the nevocellular nevus in the thymus. This is the first report of malignant melanoma in the thymus.     

Sentinel lymph node biopsy for malignant melanoma as day surgery.

Sentinel lymph node biopsy for malignant melanoma has been performed as day surgery at our hospital since August 2002. The aim of this retrospective study was to assess its feasibility compared to the inpatient procedure. METHODS: A telephone survey and review of medical records was carried out for patients who had daycase, nonhead and neck sentinel lymph node biopsy for malignant melanoma over an 18-month period. A similar matched number of inpatients were reviewed, comparing waiting times, prolonged hospital stay, complication rates and overall satisfaction. RESULTS: There were no significant differences between the two groups in terms of time from diagnosis to surgery, prolonged hospital stay and complication rates. However, in terms of overall satisfaction, 86.3% of daycase patients preferred their mode of admission whereas 52.9% of inpatients preferred their mode of admission (P=0.0003). CONCLUSIONS: Sentinel lymph node biopsy (nonhead and neck) for malignant melanoma as day surgery is feasible and confers greater patient satisfaction, increased availability of inpatient beds and cost savings without compromising patient care.     

Cutaneous malignant melanoma of the head and neck: the role of planned definitive surgery

The chart of 56 patients, consecutively operated on in our institution for malignant melanoma of the skin in the head and neck area from 1977 to 1993, were retrospectively reviewed. The follow-up was 2 to 18 years (average 7.5 years). We considered three kinds of treatment, looking at the adequacy and timing of surgery: (1) Planned definitive surgery (PDS), when surgery with adequate margins and lymph node dissection was done within two months after the initial diagnosis; (2) non-planned definitive surgery (non-PDS), when at least one of the above parameters could not be achieved; (3) and salvage surgery (Ss), for patients who presented with local recurrence or involved lymph nodes. Twenty-four patients were in the first group, ten in the second, and 22 in the third. Elective neck dissection was performed in 16 patients with a superficial spreading melanoma (SSM) or nodular melanoma (NM) lesion thicker than 1 mm, and a therapeutic radical neck dissection in 17 patients with a suspicious lymph node occurring at any stage of the disease. According to the type of surgical management, the five year survival was 90%, 60%, and 25% for PDS, non-PDS, and Ss groups, respectively (p<0.01). Patients who were initially treated with elective lymph node dissection had better prognosis than those who had therapeutic lymph node dissection (88% versus 19% at 8 years, p<0.001). These results further support the benefit of planned surgical treatment, i.e. within two months, for malignant melanoma of the head and neck. Received: 7 April 1998 / Accepted: 19 October 1998     

Is radiotherapy an effective treatment option for recurrent metastatic malignant melanoma? A case report of short-course,large-fraction radiation and a literature review

BACKGROUND

Malignant melanoma is regarded to be radiation resistant. A case of recurrent malignant melanoma with in-transit metastasis treated with short-course, high-fraction palliative radiation is presented to illustrate the effectiveness of radiotherapy.

METHOD

An 80-year-old woman initially treated surgically for a primary malignant melanoma of the left lower leg presented with multiple in-transit metastases. Palliative radiation was offered to treat two fungating in-transit masses that were resistant to treatments of isolated limb infusion and intralesional interleukin-2.

RESULTS

Treatment consisted of short-course, high-fraction radiation with 800 cGy fractions given over three weeks on days 0, 7 and 21, for a total dose of 2400 cGy. She experienced a complete response that was maintained for six months.

CONCLUSIONS

Radiation is an effective treatment option for palliation of recurrent malignant melanoma. Complete response is possible even with short-course, high-fraction radiation.     

Solitary metastatic gallbladder malignant melanoma originated from the nasal cavity: A case report

INTRODUCTIONSolitary gallbladder metastasis of malignant melanoma is rare and generally originates from skin melanoma. We report a case of gallbladder metastasis from a malignant melanoma of the nasal mucosa that was surgically treated.PRESENTATION OF CASEA 77-year-old Japanese woman diagnosed with malignant melanoma of the left sinonasal cavity three years ago underwent follow-up PET–CT and FDG uptake was detected only at the gallbladder. The nasal melanoma had been stable for the last 1.5 years after chemoradiation and her general condition was good. Cholecystectomy was performed with partial liver resection. Lymphadenectomy of the hepatoduodenal ligament was also performed. The tumor was soft and whitish, and was microscopically diagnosed as a poorly differentiated malignant melanoma that was not similar to the nasal cavity melanoma. No further metastasis is observed for more than 13 months after surgery.DISCUSSIONIn the literature, cutaneous melanoma is described as the origin of most metastatic gallbladder melanomas; however, no skin lesion was evident in this case. We believe that the poorly differentiated compartment of the nasal melanoma had metastasized to the gallbladder.CONCLUSIONFor patients with melanomas and gallbladder tumors, the possibility that metastasis could occur should be considered when selecting optimal treatment. Even when original melanoma is present, surgical treatment for gallbladder metastasis may be useful depending on the patient's conditions.     

Multicentric Malignant Melanoma in a Giant Melanocytic Congenital Nevus 20 Years After Dermabrasion in Adulthood

BACKGROUND: Dermabrasion is one approach to the treatment of treating giant melanocytic congenital nevi. Treatment is recommended to reduce the risk of spontaneous malignant transformation of giant nevi into malignant melanomas that usually occur in childhood. OBJECTIVE: To describe the development of a multicentric malignant melanoma in a giant melanocytic congenital nevus after dermabrasion. METHODS: We report about a 46-year-old male patient who developed a multicentric malignant melanoma in a giant melanocytic congenital nevus. The nevus was located on his left shoulder extending to his neck and chest. Previously, dermabrasion of the nevus was performed twice at the ages of 26 and 28. RESULTS: To our knowledge, this is the first report of malignant transformation of a giant nevus into a multicentric malignant melanoma diagnosed 20 years after the procedure of dermabrasion. CONCLUSION: We conclude that a close follow-up of such patients is mandatory.     

Highly sensitive DNA typing for detecting tumors transmitted by transplantation

DNA typing of a variable number of tandem repeats (VNTRs) and of short tandem repeats (STRs) is a modern forensic method for the identification of biological material. In many cases, amplification by the polymerase chain reaction (PCR), especially of STRs, allows DNA typing of minute amounts of or degraded DNA. Here we describe the successful use of forensic DNA typing to clarify the origin of a malignant tumor. We report two cases of metastatic malignant melanoma of unknown origin that developed a few months after transplantation in two recipients of kidneys from the same donor. Fresh metastatic tissue and blood from the first recipient, reference DNA of the donor, and only paraffin-embedded tissue from the second recipient were available for analysis. To investigate whether the melanoma originated in the donor, DNA analysis of nine polymorphic loci was performed. The results of the analysis showed that, in both cases, the tumors were genetically different from the recipient DNA but matched the donor DNA. One incident of allele loss was attributed to a mutation event. We conclude that the metastatic melanoma in both recipients originated in the donor and was transmitted by renal transplantation.

Primary malignant melanoma of the gasserian ganglion associated with neurofibromatosis

A case of primary intracranial malignant melanoma of the left gasserian ganglion associated with temporal lobe gliosis in a patient suffering from von Recklinghausen's disease is reported. The association of primary malignant melanoma of the trigeminal nerve and neurofibromatosis is discussed.     

Gamma knife radiosurgery for malignant melanoma in the paranasal sinuses: case report

A case of malignant melanoma in the paranasal sinuses, successfully treated with gamma knife stereotactic radiosurgery, is reported. A 90-year-old man with left periorbital swelling was referred to our hospital for gamma knife radiosurgery. He had a 4-month history of left periorbital swelling and ophthalmalgia, but he was treated conservatively due to his age. CT showed a large mass with bone destruction located in the nasal cavity, paranasal sinuses, and orbita. A 15 Gy peripheral dose was administered to the upper portion of the tumor with the gamma knife technique, at the 50% isodose line using a 18 mm collimator (21 shots). Seven months after radiosurgery, his left periorbital swelling was improved markedly, and CT showed a significant reduction in the volume of the tumor. Gamma knife radiosurgery is a feasible treatment for malignant melanoma in the paranasal sinuses. It provides excellent quality of life, less injury to the patient, and fewer side effects than other treatment strategies.     

Simultaneous double interphalangeal dislocation on a single finger

The authors report a rare case of the simultaneous double interphalangeal dislocation in the little finger of the left hand. A 35-year-old man, playing football as a goalkeeper, was injured when another player trod on his little finger. The dislocation was reduced by traction without anesthesia and the finger was immobilized on a splint. Although the patient removed the splint only a week later and failed to come for a check-up, at 1 year, his little finger showed no deformity and regained a full range of painless, active motion.     

Utility of perioperative skin perfusion pressure measurement for treatment of ulcers caused by arteriovenous access ischaemic steal

Arteriovenous access ischaemic steal is a serious complication following arteriovenous fistula (AVF) construction. The aim of treatment is to improve distal circulation without impairing the function of the fistula. Therefore, any repair should be performed with intraoperative monitoring. We report 2 cases of this disorder treated using perioperative measurement of skin perfusion pressure (SPP) for preoperative surgical planning and intraoperative guidance. A 73‐year‐old woman with a left cubital AVF developed gangrene of the tip of the left little finger. Arteriovenous access ischaemic steal was suspected. The SPP of the little finger was 18 mm Hg, which increased to 65 mm Hg after manual occlusion of the fistula. A 58‐year‐old woman with a left antebrachial AVF had gangrene of the tip of the left middle finger. The SPP was 19 mm Hg, and steal syndrome was suspected based on angiography and the SPP with manual occlusion of the fistula. In both cases, serial plication of the fistula was performed based on intraoperative perfusion pressure monitoring, leading to the successful resolution of the ischaemic steal syndrome. In both cases, haemodialysis could be continued through the repaired fistula.
