ABSTRACT
BACKGROUND: Chronic lymphoedema is classically complicated by recurring episodes of cellulitis. Degeneration to the angiosarcoma form (Stewart-Treves syndrome) is much less common. It occurs mainly in the upper limbs following surgery or radiotherapy for mammary neoplasia. Herein we report a rare case of Stewart-Treves syndrome (STS) of the lower limb as a complication of congenital lymphoedema. PATIENTS AND METHODS: A 69-year-old woman treated for bilateral lower-limb oedema present for 30years developed painful necrotic lesions in her left lower limb. A diagnosis of angiosarcoma was made based on biopsy of a nodular lesion. Since surgical excision was precluded by the extent of the lesions, chemotherapy was initiated with paclitaxel 175mg/m2 every 21days. The outcome was rapidly unfavourable and the patient died at her home during the third course of treatment. DISCUSSION: Angiosarcoma is an extremely rare complication of primary lymphoedema; treatment is poorly codified and the prognosis is unfavourable.

BACKGROUND: The inflammatory myopathies are a heterogeneous group of muscle diseases and comprise polymyositis, dermatomyositis (DM), myopathies associated with cancers, necrotising myositis and inclusion body myositis. DM occasionally exhibits few or no muscular signs: i.e. hypomyopathic/amyopathic DM. Anti-MDA5 dermatomyositis (DM) is a rare form of dermatomyositis that is frequently amyopathic; the prognosis is linked mainly to pulmonary involvement. PATIENTS AND METHODS: A 69-year-old woman treated for mucosa-associated lymphoid tissue (MALT) gastric lymphoma was referred for a bullous eruption. Based on the investigations performed, a diagnosis was made of bullous pemphigoid. At the same time, amyopathic dermatomyositis was discovered together with interstitial lung disease. Systemic steroids were introduced in combination with rituximab. A favourable outcome was achieved. DISCUSSION: Anti-MDA5 dermatomyositis must be considered systematically in all cases of pulmonary involvement associated with cutaneous signs of dermatomyositis, in which no muscular involvement is generally seen. This condition accounts for up to 7% of DM and carries a severe prognosis due to pulmonary involvement.

BACKGROUND: Head and neck melanomas (HNMs) account for an increasing proportion of melanomas and have a poor prognosis. OBJECTIVES: To compare the clinical and histological characteristics of HNMs with those of melanomas at other sites (MOS), and to identify pertinent clinicopathological subgroups of HNM. METHODS: A retrospective population-based study of incident in situ and invasive melanomas in the period 2004-2011 was performed. RESULTS: HNMs represented 26·7% of 1548 melanomas, corresponding to a density ratio of 3·7 between HNMs and MOS. HNMs occurred later than MOS (71·2 vs. 58·4 years; P < 0·01), included a higher proportion of in situ cases (49·6% vs. 13·5%; P < 0·01) and were mainly lentigo malignant melanomas (73·0% vs. 2·6%; P < 0·01). Invasive HNMs included a higher proportion of thick (> 2 mm) tumours [33·7% vs. 24·1% (P = 0·01); mean Breslow thickness: 2·18 vs. 1·77 mm (P = 0·03)] and nodular melanomas (20·1% vs. 12%; P < 0·01). HNMs in the peripheral area of the head and neck differed from those of central location by a younger age of onset (65·2 vs. 72·4 years; P < 0·01), male predominance (64·4% vs. 33·8%; P < 0·01), and higher proportions of invasive (67·2% vs. 42%; P < 0·01) and nodular (15·1% vs. 7·5%; P = 0·01) melanomas. CONCLUSIONS: HNMs highly differ from MOS, and are clinically and histologically heterogeneous, possibly as a consequence of different patterns of sun exposure. These data could help to improve primary and secondary prevention messages for patients and doctors.

BACKGROUND: The most prevalent subtype of breast cancer (BC) is luminal hormonal-positive breast cancer. The neoadjuvant chemotherapy regimens have side effects, emphasizing the need to identify new startegies. OBJECTIVE: Analyze the complete pathologic response (pCR) rate and overall response in a low-risk hormone-positive subset of patients receiving neoadjuvant hormone treatment (NAHT) with or without Palbociclib (a CDK4/CDK6 inhibitor) to boost NAHT effectiveness. MATERIALS AND METHODS: Based on the upfront 21-gene Oncotype DX or low-risk Breast Recurrence Score assay (RS™), the SAFIA trial is designed as a prospective multicenter international, double-blind neoadjuvant phase-III trial that selects operable with luminal BC patients that are HER2-negative for the induction hormonal therapy with Fulvestrant 500 mg ± Goserelin (F/G) followed by randomization of responding patients to palbociclib versus placebo. The pCR rate served as the study's main outcome, while the secondary endpoint was a clinical benefit. RESULTS: Of the 354 patients enrolled, 253 initially responded and were randomized to either F/G fulvestrant with palbociclib or placebo. Two hundred twenty-nine were eligible for the evaluation of the pathologic response. No statistically significant changes were observed in the pCR rates for the patients treated with the F/G therapy with placebo or palbociclib (7% versus 2%, respectively) per the Chevallier classification (Class1 + Class2) (p = 0.1464) and 3% versus 10% assessed per Sataloff Classification (TA, NA/NB) (p = 0.3108). Palbociclib did not increase the rate of complete pathological response. CONCLUSION: Neoadjuvant hormonal therapy is feasible in a selected population with a low RS score of < 31 CLINICAL TRIAL: NCT03447132.
