Sex: M, Age: 47 years old
Diagnosis: lymph node metastases of right groin from melanoma in the epigastric region.
Excision of supraumbilical nevoid lesion on (approx 7-8 months before this report) for which the histological diagnosis gives evidence for: "malignant melanoma growing vertically, Clark level III, 0.10 Breslow thickness. The edges of the surgical resection cover the entire lesion (approximately 0.1 – 0. cm)."
Subsequently, further tests were performed that turned out to be negative for metastases, specifically:Chest X-ray; echo tomography soft tissue of axillary and inguino-crural areas; full body CAT scan.
Following performance of lymph scintigraphy, the patient underwent an operation to enlarge the previous nevus resection and a sentinel node biopsy of the right groin was performed at the Regional Reference Centre for Cutaneous Melanoma – IOV – Padua.After removing 4 lymph nodes in the right groin area, one resulted positive for sub capsular and intraparenchymal micrometastasis of melanoma with multiple foci (maximum diameter 0.61 mm, SII Starz sec).
Revision in Padua of the first histological test with class worsening:Superficial-extension malignant melanoma, in vertical-growth phase, non-ulcerated, with low mitotic index (o mitosis/mm²), with plentiful brisk type lymphocytic infiltrate and areas of regression, Clark level IV, maximum thickness of the lesion under Breslow 1.14 mm. Edges of resection undamaged.
Given the positivity of the sentinel node, approx. 5 months before report the patient underwent a surgical right inguinal-iliac-obturator lymphadenoidectomy, which resulted negative (21 lymph nodes removed).The post-operative course was complicated by the appearance of significant lymphocoele that gradually reduced toward approx. 2 months later.
In consideration of the stage of the disease (pT2a N1a -> IIIA), an adjuvant treatment with Interferon as part of the Mel. A. The study was proposed to the patient.This treatment began on approx 4 months before report, and the patient was assigned to Arm A (IFN with high intensified doses), with a protocol schedule of 4 cycles, each lasting 1 month, with intervals of 1 month of suspension as in the calendar provided below:
Cycle start dateLast dose date
1st cycle ev., (4 months before report) (approx 1 month later)
2nd cycle ev. (2 months before) (1 month later)
3rd cycle ev. (several weeks before) (patient almost through)
4th cycle ev. (this treatment to begin shortly and last for month)
Towards the end of the first cycle, the specialized oncological examination during the 1st cycle found out that the patient showed good tolerance to the treatment, so that no reduction in dose was required.
A marked edema appeared on the right leg, for which the patient presented for examination between first and second treatment cycles; the oncology specialist interpreted this edema as the direct result of the procedure to empty the right inguinal-iliac-obturator, however recommended, as a precaution, a venous echo Doppler of the lower limb that excluded a deep venous thrombosis.
Follow-up blood tests were performed during the treatment with IFN, the results are enclosed.
Approx 2 months before report, excision of another nevoid lesion on the right thigh giving histological evidence for "compound freckled nevus with moderate degree of dysplasia – entire lesion within the borders of the resection".
The ultrasound of the lower abdomen on, shows at the level of the inguinal regions:
“On the right oedematous thickening of the soft tissues in relation to recent results of surgery."
Some lymph nodes were found in the left inguinal area, in the medial planes, the largest measuring 1.6 – 1.8 cm.
Due to the worsening of the lymphedema, the patient underwent an additional oncological examination 11/2 month before report, with recommendation to repeat a venous Doppler that confirms a "situation likely secondary to a serious lymphostasis, provoked by inteventions in the lymphatic system, although at this time it is not possible to exclude components related to the primary pathology."Therefore a cycle of manual lymphatic drainage is recommended with elasto-compressive bandage performed by the patient.
The most recent available tests concern blood tests (earlier the same month and left groin ultrasound:"significant numerous lymph node formations with reactive character and maximum diameter of 18 mm.No evidence of nodular-type aspects").
