Paraneoplastic Dermatoses Associated With Gynecologic and Breast Malignancies

Paraneoplastic dermatomyositis associated with urothelial cancer: report of a case and systematic review of the literature

Background

The idiopathic inflammatory myopathies (IIM) are a collection of autoimmune diseases that have a substantial impact on the entire body and include conditions such as dermatomyositis (DM), polymyositis (PM), sporadic inclusion body myositis, and immune-mediated necrotizing myopathy. These disorders are characterized by symptoms such as muscular weakness, pain, and dermal rash. This systematic review is intended to explore the potential link between bladder cancer and DM/PM.

Methods

We performed a comprehensive systematic search on PubMed and Scopus until August 2022 to identify relevant research studies. The studies that met our inclusion criteria focused on patients with urinary bladder cancer and dermatomyositis, and/or polymyositis.

Results

The patients' median age was 65.5 years (47-79), with the majority being male (15, 39.47%). Bladder cancer manifested before PM/DM in 5 (13.15%) patients, while in the majority of cases occurred after the cancer diagnosis. The stage of cancer at the time of the initial PM/DM diagnosis were mostly locally (11/20, 50%).During the first presentation, the patients had a median creatine kinase level of 2227 U/L, ranging between 44 and 10471. In one case, anti-TIF-1γ antibodies were found to be present. Among the cases with reported medical history (20/38), treatment immediately improved DM symptoms in 16 patients(53.8%) and in 3 patients(15%), symptoms of DM resurfaced during the period after the operation. Death was reported in 14 (36.8%) patients.

Conclusion

In conclusion, our study provides knowledge and understanding for identifying specific risk factors in patients with the coexistence of bladder cancer and DM/PM and their management. During the initial and follow-up screening, age, gender, and the clinicopathological subgroup of myositis should be considered to ensure proper management of the condition.

Paraneoplastic Dermatomyositis in a Case of Gallbladder Signet Ring Cell Carcinoma

Dermatomyositis (DM), as a paraneoplastic presentation, is rare, though the incidence of malignancies in patients with DM is very high. While it has been reported with a wide range of cancers, association with gallbladder carcinoma is uncommon. Furthermore, signet ring cell carcinoma detected in the metastasis presumably from our patient's gallbladder mass is itself a rare and highly malignant variant of gallbladder adenocarcinoma. Thus, this association can be considered to be a very novel finding. 

We describe the case of a 64-year-old Indian man who presented with cervical lymph node swelling concurrent with facial rashes, periorbital oedema, nasal regurgitation, dysphagia and weakness in his limbs. The presence of characteristic Gottron’s papules and shawl-like truncal rash on examination led to the diagnosis of DM. Fine needle aspiration cytology (FNAC) of the cervical lymph nodes revealed metastatic signet ring cells, and contrast-enhanced CT (CECT) scan of the abdomen showed a significant gallbladder mass with liver infiltration, thus confirming the underlying association.

Acanthosis Nigricans - A Two-Sided Coin: Consider Metabolic Syndrome and Malignancies!

BACKGROUND

Acanthosis nigricans (AN) is acquired hyperpigmentation of the intertriginous body regions. Histologically, AN is characterised by a thickened stratum corneum and a variable amount of acanthosis. Although benign and rarely symptomatic, AN may be a red flag for underlying pathologies.

CASE PRESENTATION

We analysed our patients with AN and could differentiate three different patterns, that are illustrated by one case report each. The is the benign AN associated with metabolic syndrome including obesity. The second type is the paraneoplastic AN malignancy which is associated with a wider range of malignancies. This type may occur before, after or with the clinical appearance of the malignancy. The third type is relapsing AN after complete remission. We present a patient who had a malignant AN and was treated successfully for his cancer. Years later, however, AN relapsed. In that case in association with the appearance of skin tags. Cancer restaging excluded a tumour relapse. His BMI was 31.2 kg/m², and the diagnosis of benign AN was confirmed.

CONCLUSIONS

The diagnosis of AN remains incomplete without screening for metabolic syndrome and/ or cancer. The combination of AN and skin tags is more often associated with metabolic syndrome. AN may be considered as a red flag for malignancies and the metabolic syndrome.

Cutaneous paraneoplastic syndromes

A variety of cutaneous abnormalities can be seen in patients with malignant diseases, some of which are infectious, with others representing direct involvement of the skin by the underlying disorder. Yet another group of lesions can be regarded as associated markers of the malignant process, and, as such, are termed "paraneoplastic." This review considers the latter collection of conditions, grouping them by the generic type of malignancy that is usually linked to the paraneoplasia. Some of the processes show a predominant association with alimentary tract malignancies (acanthosis nigricans, acrodermatitis paraneoplastica, florid cutaneous papillomatosis, necrolytic migratory erythema, palmoplantar keratoderma, pancreatic fat necrosis, and pityriasis rotunda). Others are usually linked to a hematolymphoid malignancy (acquired ichthyosis, exfoliative erythroderma, necrobiotic xanthogranuloma, pemphigus paraneoplastica, plane xanthoma, pyoderma gangrenosum, scleromyxedema, Sweet syndrome, and leukocytoclastic vasculitis). Finally, yet another collection of paraneoplastic skin disorders can associate themselves with anatomically-diverse malignancies (Leser-Trelat syndrome, Trousseau syndrome, dermatomyositis, erythema gyratum repens, hypertrichosis lanuginosa acquisita, papuloerythroderma of Ofuji, tripe palms, and multicentric reticulohistiocytosis). Recognition of these processes by the pathologist can be a valuable step in the characterization of underlying malignant diseases.

Dermatomyositis as an extrahepatic manifestation of hepatitis B virus-related hepatocellular carcinoma: A case report and literature review

RATIONALE

Dermatomyositis is an idiopathic inflammatory myopathy with specific cutaneous manifestations, which is closely associated with malignancy. However, the exact mechanism remains elusive. Even less is known about dermatomyositis with hepatocellular carcinoma (HCC).

PATIENT CONCERNS

We reported a case of dermatomyositis with hepatitis B virus (HBV) infection. He incidentally found his lower limbs little weakness accompanied with his wrist erythema. He was found HBsAg positive for forty years with slightly positive of α-fetal protein (AFP).

DIAGNOSES

A dermapathology from his hand-wrist lesions demonstrated a scattered inflammatory infiltrate around the capillaries of the dermis. Abdominal enhanced computer tomography (CT) revealed infiltrative HCC affecting the whole liver, accompanied by liver metastasis and liver cirrhosis. Liver tumor needle biopsy pathology showed HCC with moderate differentiation. The left supraclavicular lymph node needle biopsy pathology confirmed metastasic HCC.

INTERVENTIONS

Prednisolone was gradually withdrawn with the introduction of Entecavir 0.5 mg daily. Radiofrequency ablation therapy for liver tumor was performed once in order to decrease the tumor load.

OUTCOMES

His muscle power improved to grade 4+/5 in the lower limb one month after anti-HBV treatment. However, this patient died finally from liver failure due to the development of liver tumor.

LESSONS

In the coming clinic work, we must pay more attention to the extrahepatic disorder induced by HBV. On treating experience, glucocorticoid administration is often contraindicated for HBV infected patients because of its potential promotion of HBV replication. Thus, it is necessary to administrate high-effective anti-HBV drug prior to glucocorticoid treatment in order to prevent liver failure.

Umbilical Lesions: Clinicopathologic Features of 99 Tumors

Background. Umbilical lesions are rare, and can be benign or malignant. This retrospective study was conducted to assess the epidemiological, clinical, and histologic characteristics of umbilical masses. Methods. Cases of umbilical masses from January 1994 to August 2016 were retrieved from our institution’s pathology databases, and their clinicopathological features were reviewed. Results. There were a total of 99 cases of umbilical masses, 78 women (78.8%) and 21 men (21.2%). Of these, 59 were malignant (59.6%) and 40 were benign (40.4%). Among the malignant cases, 48 were women with a mean age of 65 years and 11 were men with a mean age of 66 years. All malignant lesions were secondary tumors. Twenty-five patients (42.3%) had a metastatic tumor to the umbilicus with an average of 7 months from the original diagnosis (12 gynecological, 8 pancreatic/gastrointestinal, 2 lymphomas, and a case each of breast, prostate, and melanoma). Of the patients with a benign diagnosis, 30 were women (75%) with a mean age of 52 years and 10 were men (25%) with a mean age of 43 years. The benign lesions included epidermal inclusion cysts (15/40), endometriosis (11/40), lipomas (3/40), neurofibromas (3/40), fibromas (3/40), abscesses (2/40), and 1 case each of tubular apocrine adenoma, serous cystadenoma, and calcified nodule. Conclusion. The most common metastatic tumors to the umbilicus are from the adjacent organs with the gynecologic tract as the most frequent primary followed by the gastrointestinal system. Primary malignant tumors of the umbilical region are rarely identified in clinical practice.

Paraneoplastic syndromes associated with gynecological cancers: A systematic review

A number of paraneoplastic syndromes have been described with gynecological cancers. These syndromes are induced by substances secreted by the tumor or by an immune response triggered by the cancer. Each system of the human body can be affected by different syndromes. Indeed, paraneoplastic syndromes occurring from tumors of the gynecologic tract were found to involve the nervous, ophthalmologic, dermatologic, rheumatologic, endocrine, hematologic and renal systems. These syndromes can manifest before, at the time, or after the diagnosis of cancer. They can also occur at the time of a recurrence. Knowledge about these syndromes is important for physicians caring for patients with cancers, as they can result in severe morbidity and must be treated appropriately. Literature regarding paraneoplastic syndromes associated with tumors of the female genital tract is scattered and the subject has not been reviewed recently. A systematic literature search was thus conducted to identify paraneoplastic syndromes associated with gynecologic cancers. This review focuses on the cancers involved with each paraneoplastic syndrome, and on their pathophysiology, clinical manifestations, possible complications, outcomes, and treatments. As the mainstay of treatment in these conditions is often to address the underlying tumor, it is of upmost importance that physicians be aware of these rare cancer manifestations.

A rare case of severe myositis as paraneoplastic syndrome on breast cancer

BACKGROUND

Dermatomyositis and polymyositis are both types of idiopathic inflammatory myositis characterized by inflammation and weakness of proximal skeletal muscles and skin rash.

CASE

A 49-year-old Caucasian woman recently diagnosed with breast cancer classified as T1N2M0, stage IIIA, presenting skin rash associated with heliotrope and Gottron's papules. In addition, there was a progression to a severe reduction in proximal muscle strength with severe dysphagia. The initial treatment was conducted, and the patient recovered from all symptoms and followed adjuvant cancer management.

TREATMENT

At first, high dose of corticosteroid was administered as pulse therapy, and a radical mastectomy was indicated due to the severe symptoms of the paraneoplastic syndrome. Then chemotherapy and radiotherapy were applied, and oral corticoid associated with immunosupressive drug was administered for dermatomyositis control.

DISCUSSION

The association between myositis and an increased risk of cancer has been demonstrated over the years. This patient has a high probability of dermatomyositis diagnosis. The initial treatment with high dose of glucocorticoids may result in an improvement of muscle lesions. Second-line treatment with azathioprine, methotrexate, or cyclophosphamide may be required for aggressive disease. Removal of the cancer induces improvement of paraneoplastic syndrome.

CONCLUSION

Dermatomyositis can be a clinical manifestation of a paraneoplastic syndrome in patients with breast cancer. It is a rare diagnosis, and there is little evidence to guide treatment until now. It is possible to control the evolution of dermatomyositis with high doses of glucocorticoids in almost all cases; however, in severe cases of paraneoplastic syndrome, cancer treatment should start immediately.
