Ovarian cancer and gangrene of the digits: case report and review of the literature

Digital ischaemia as a presenting feature in metastatic ovarian cancer

A woman in her 50s presented with acute pain and discolouration in the fingertips of both hands, without other features of connective tissue disease. The history was otherwise significant for abdominal bloating, altered bowel habit, urinary urgency and fatigue. Inflammatory markers, antinuclear antibodies, serum protein electrophoresis and complement levels were all normal. The tumour marker CA125 was significantly elevated, prompting a CT abdomen and pelvis, which revealed a large right-sided adnexal mass with multiple enhancing peritoneal and omental nodules and moderate ascites, suggestive of disseminated primary ovarian cancer.Digital ischaemia (DI) can be associated with cancer in up to 15% of cases. An underlying cancer should be suspected in patients presenting with new or worsening symptoms of DI. Prompt treatment with anticancer therapies can achieve complete resolution of DI.

Paraneoplastic acral vascular syndrome: case presentation and literature review

A 65-year-old man, a smoker, presented to the emergency department with progressive digital ischaemia, fever and weight loss. The clinical examination revealed generalised lymphadenopathy and ischaemic changes of the right distal phalanges of the second, third and fourth fingers. He had an ultrasound-guided biopsy of the cervical lymph node, which showed histopathological findings of classic Hodgkin's lymphoma. Paraneoplastic acral vascular syndrome (PAVS) is a rare phenomenon and seen more in solid malignancies. There are very few reported cases of PAVS in haematological malignancies, including Hodgkin's lymphoma. This case highlights the idea that the presence of acral vascular syndrome-especially in older patients-should alert physicians to search for an underlying malignancy as part of the medical evaluation. Also, it shows that medical treatment may slow the progress of the digital ischaemia until the culprit tumour has been identified and treated.

Raynaud's phenomenon as a presenting manifestation of ovarian cancer: A case report

Raynaud's phenomenon (RP) is characterized by episodes of vasospasm affecting the hands and feet. Paraneoplastic RP, as a single presenting symptom is rarely seen in cases of ovarian cancer (OC), and thus may lead to misdiagnosis. We present a case of paraneoplastic RP in a patient with high-grade serous OC. A 66-year-old female presented with dyspnea and bilateral peripheral cyanosis involving her fingers. CA125 was elevated (423 U/mL). CT revealed a pleural effusion on the left side, suspicious omental lesions and ascites. Omental biopsy and pleural cytology demonstrated high-grade serous OC. Neoadjuvant chemotherapy (carboplatin/paclitaxel) resulted in objective improvement in finger ischemia and complete regression of vasospastic features. However, the patient's disease was refractory to post-surgical treatment and eventually she deceased of multiple organ failure. To conclude, RP may be a presenting symptom of OC. It is important to determine the underlying disease and develop an effective treatment strategy.

[Digital necrosis revealing lung cancer: Case-report and review of the literature]

We report the case of a 51-year-old patient who presented necrosis affecting all of the toes in a context of confusion and declining general health. The etiology work-up disclosed a lung mass. Biopsy and search for extension led to the diagnosis of adenocarcinoma with liver metastasis. Unfortunately, symptomatic treatment of the digital necrosis did not lead to improvement and the patient was given palliative care. Digital necrosis generally affects the fingers. Localization on the toes is atypical and few cases have been reported in the literature.

Causes and outcomes of finger ischemia in hospitalized patients in the intensive care unit

OBJECTIVE

Vascular surgeons may be consulted to evaluate hospitalized patients with finger ischemia. We sought to characterize causes and outcomes of finger ischemia in intensive care unit (ICU) patients.

METHODS

All ICU patients who underwent evaluation for finger ischemia from 2008 to 2015 were reviewed. All were evaluated with finger photoplethysmography. The patients' demographics, comorbidities, ICU care (ventilator status, arterial lines, use of vasoactive medications), finger amputations, and survival were also recorded. ICU patients were compared with concurrently evaluated non-ICU inpatients with finger ischemia.

RESULTS

There were 98 ICU patients (55 male, 43 female) identified. The mean age was 57.1 ± 16.8 years. Of these patients, 42 (43%) were in the surgical ICU and 56 (57%) in the medical ICU. Seventy (72%) had abnormal findings on finger photoplethysmography, 40 (69%) unilateral and 30 (31%) bilateral. Thirty-six (37%) had ischemia associated with an arterial line. Twelve (13%) had concomitant toe ischemia. Eighty (82%) were receiving vasoactive medications at the time of diagnosis, with the most frequent being phenylephrine (55%), norepinephrine (47%), ephedrine (31%), epinephrine (26%), and vasopressin (24%). Treatment was with anticoagulation in 88 (90%; therapeutic, 48%; prophylactic, 42%) and antiplatelet agents in 59 (60%; aspirin, 51%; clopidogrel, 15%). Other frequently associated conditions included mechanical ventilation at time of diagnosis (37%), diabetes (34%), peripheral arterial disease (32%), dialysis dependence (31%), cancer (24%), and sepsis (20%). Only five patients (5%) ultimately required finger amputation. The 30-day, 1-year, and 3-year survival was 84%, 69%, and 59%. By Cox proportional hazards modeling, cancer (hazard ratio, 2.4; 95% confidence interval, 1.1-5.6; P = .035) was an independent predictor of mortality. There were 50 concurrent non-ICU patients with finger ischemia. Non-ICU patients were more likely to have connective tissue disorders (26% vs 13%; P = .05) and hyperlipidemia (42% vs 24%; P = .03) and to undergo finger amputations (16% vs 5%; P = .03).

CONCLUSIONS

Finger ischemia in the ICU is frequently associated with the presence of arterial lines and the use of vasopressor medications, of which phenylephrine and norepinephrine are most frequent. Anticoagulation or antiplatelet therapy is appropriate treatment. Whereas progression to amputation is rare, patients with finger ischemia in the ICU have a high rate of mortality, particularly in the presence of cancer. Non-ICU patients hospitalized with finger ischemia more frequently require finger amputations, probably because of more frequent connective tissue disorders.

Digital necrosis with squamous cell carcinoma of the tonsil

Background

Digital necrosis is a rare phenomenon of paraneoplastic syndrome associated with squamous cell carcinoma of the tonsil. Since 1965, more than 70 cases have been reported worldwide in the literature.

Case report

A 54-year-old male smoker presented with Raynaud’s phenomenon, proceeding to frank gangrene of the fingers. Working up the case finally pointed toward carcinoma of the tonsil as the underlying cause – a rare paraneoplastic manifestation.

Conclusion

No definite etiology has been found to be the cause of Raynaud’s phenomenon in this case of the squamous cell carcinoma of the tonsil. A brief discussion of the literature is also presented.

Digital ischemia associated with cancer: results from a cohort study

Digital ischemia associated with cancer (DIAC) is increasing in frequency and recent reports have suggested the concept of paraneoplastic manifestation. The aims of this study were to characterize the clinical presentation of DIAC and identify clinical features that could lead physicians to diagnose underlying cancer.From January 2004 to December 2011, 100 patients were hospitalized in the Department of Internal Medicine at Rouen University Hospital, France for a first episode of DI. Fifteen (15%) exhibited symptomatic or asymptomatic cancer during the year preceding or following vascular episode and constituted the DIAC group. Other patients without cancer made up the digital ischemia (DI) group.Median time between diagnosis of cancer and episode of digital necrosis was 2 months [0.25-9]. Diagnosis of DI and concomitant cancer was made in 7 of the 15 patients, while DI preceded the malignant disorder in 2 cases and followed it in 6 cases. Histological types were adenocarcinoma for 7 (46.7%), squamous cell carcinoma for 4 (26.7%), and lymphoid neoplasia for 3 patients (20%). Six patients (40%) had extensive cancer. Three patients were lost to follow-up and 5 patients died <1 year after diagnosis of cancer. Cancer treatment improved vascular symptoms in 6 patients (40%). Patients with DIAC, compared to patients with DI, were significantly older (56 years [33-79] vs 46 [17-83] P =0.005), and had significantly lower hemoglobin and hematocrit levels (12.7 g/dl vs 13.9 g/dl; P =0.003 and 38% vs 42%; P =0.003, respectively). Patients with DIAC had a higher platelet rate (420 vs 300 G/L P =0.01), and 6 patients with DIAC (40%) had thrombocytosis. There was no difference between groups either in C-reactive protein level (12 mg/L vs 5 mg/L; P =0.08) or regarding cardiovascular risk factors, presence of autoimmunity, or monoclonal protein.This retrospective study suggests that DIAC may be more prevalent than previously reported. Outcomes of the 2 diseases were not strictly chronologically parallel. However, in the majority of cases, treatment of the tumor resolved vascular involvement. Our findings suggest that age >50 years and thrombocytosis should alert physicians to consider a possible occult malignancy when digital necrosis occurs.

[Acral necrosis in metastatic ovarian carcinoma. A single episode of Moschowitz syndrome during gemcitabine chemotherapy]

For some time now, there have been reports of acral necrosis as a paraneoplasia that may occur in association with a number of different malignant tumours. There have also been a series of reports about acral necrosis associated with chemotherapy with various cytostatics. The treatment of choice if these lesions occur is plasmapheresis. Ultimately, the occurrence of thrombotic microangiopathy (TMA) can only be prevented by close monitoring through regular laboratory controls before each new cycle of chemotherapy. In the differential diagnosis, Raynaud's syndrome should be considered as a premonitory paraneoplasia, a risk factor for the occurrence of acral necrosis in patients with a malignant tumour undergoing chemotherapy, particularly patients with ovarian carcinoma receiving gemcitabine treatment.

Rheumatic syndromes associated with malignancy

The relation between rheumatic syndromes and an underlying malignancy is a complex one. As a result of autoimmunity, an aberrant immune response, or the use of immunomodulatory drugs, many of the rheumatic diseases appear to pose an increased risk for the development of malignancy. Unfortunately, for many of the same reasons, the presence of an underlying malignancy can result in the development of features of rheumatic disease. Awareness of the associations between rheumatic syndromes and malignancy will aid the clinician in the accurate diagnosis of underlying pathology, more effective treatment of both the symptoms and underlying disease, and appropriate surveillance for the development of later complications.

Digital necrosis associated with squamous cell carcinoma of the tonsil

BACKGROUND

Digital necrosis is an uncommon paraneoplastic syndrome. Fewer than 50 cases have been sporadically reported through the literature over the last 30 years.

CASE REPORT

We describe the unfortunate case of a 62-year-old woman with a locally advanced squamous cell carcinoma of the tonsil. She was admitted to the hospital for symptomatic hypercalcemia and was found to have metastatic disease. She subsequently had digital necrosis develop. Despite numerous attempts to control the rapidly progressive ischemia, little objective evidence of response was noted. Her primary disease did not respond to palliative radiation, and her general condition rapidly deteriorated.

CONCLUSIONS

A review of the literature provided some insight into the possible etiology of this unique complication of malignancy. Unfortunately, the treatment options suggested were of limited value, because there was no discernible benefit with any directed treatment. A brief summary and discussion of the literature follows.

Paraneoplastic acral vascular syndrome: epidemiologic features, clinical manifestations, and disease sequelae

BACKGROUND

Acral vascular syndromes associated with malignancy have rarely been reported.

OBJECTIVE

Our purpose was to assess the clinical and evolving features of paraneoplastic acral vascular syndromes.

PATIENTS AND METHODS

Two cases of paraneoplastic gangrene are described and analyzed together with previously reported cases identified by a MEDLINE search.

RESULTS

Among the 68 patients identified, 40 had gangrene, 16 had acrocyanosis, and 12 had Raynaud's phenomenon. The male to female ratio was 0.89; median age was 59 years. Fingers were affected in 94%. Adenocarcinomas were the predominant associated malignancies (41%), and metastases were observed in 41%. The acral vascular syndromes in 48% of the patients definitively regressed after tumor treatment. Forty-four percent of the patients died within 2 years. A favorable cutaneous outcome was obtained with prostacyclin infusions in 6 patients.

CONCLUSION

A neoplastic origin of acral vascular syndrome should be considered in elderly patients, especially men, in the absence of usual causative conditions.
