In humans, phyllodes tumors of the breast are rare fibroepithelial tumors that are further characterized as benign, borderline, or malignant according to their histomorphologic features. Phyllodes tumors are poorly responsive to treatment other than excision. NHP have a much lower frequency of mammary neoplasia than do humans, and none of the lesions reported previously in NHP are consistent with phyllodes tumors. Here we present the case of a mammary tumor in a northern greater galago (Otolemur garnettii) that was histologically characteristic of a malignant phyllodes tumor...

Merkel cell carcinoma (MCC) is a rare, highly aggressive tumor, and local or regional disease recurrence is common, as is metastasis. MCC usually develops in sun-exposed skin in patients of advanced age. Its incidence has risen 4-fold in recent decades as the population has aged and immunohistochemical techniques have led to more diagnoses. The pathogenesis of MCC remains unclear but UV radiation, immunosuppression, and the presence of Merkel cell polyomavirus in the tumor genome seem to play key roles. This review seeks to update our understanding of the epidemiology, etiology, pathogenesis, and clinical features of MCC...

BACKGROUND: Epidermal growth factor receptor (EGFR) mutations occur in about 50% of Asian patients with non-small cell lung cancer (NSCLC). Patients with advanced NSCLC and EGFR mutations derive clinical benefit from treatment with EGFR-tyrosine kinase inhibitors (TKIs). This study assessed the efficacy and safety of adjuvant icotinib without chemotherapy in EGFR-mutated NSCLC patients undergoing resection of stage IB-IIIA. METHODS: Our retrospective study enrolled 20 patients treated with icotinib as adjuvant therapy...

Here we present, to the best of our knowledge, the first case of a paraneoplastic Cushing's syndrome (hypercortisolism) resulting from treatment-related neuroendocrine prostate cancer - a highly aggressive and difficult disease to treat. A 51-year-old man was started on androgen deprivation therapy after presenting with metastatic prostate cancer, characterized by diffuse osseous metastasis. Shortly thereafter, he developed progressive disease with biopsy proven neuroendocrine prostate cancer as well as symptoms of increased skin pigmentation, hypokalemia, hypertension, hyperglycemia and profound weakness, consistent with ectopic Cushing's syndrome...

Erythema annulare centrifugum (EAC) is a clinical reaction pattern that includes lupus erythematosus, spongiotic dermatitis (particularly pityriasis rosea), pseudolymphoma and cutaneous B-cell lymphoma. However, it can be the result of cutaneous metastasis by an internal carcinoma. We present the case of a 38-year-old woman with bilateral inflammatory breast cancer following multimodal therapy. After chemotherapy, the patient developed EAC on her back, clinically suspect of subacute cutaneous lupus erythematosus...

We review the most characteristic clinical and histopathologic findings of the cutaneous manifestations of the occlusive nonvasculitic vasculopathic disorders. Clinically, most of these conditions are characterized by retiform purpura. Histopathologic findings consist of occlusion of the vessel lumina with no vasculitis. Different disorders may produce nonvasculitic occlusive vasculopathy in cutaneous blood and lymphatic vessels, including embolization due to cholesterol and oxalate emboli, cutaneous intravascular metastasis from visceral malignancies, atrial myxomas, intravascular angiosarcoma, intralymphatic histiocytosis, intravascular lymphomas, endocarditis, crystal globulin vasculopathy, hypereosinophilic syndrome, and foreign material...

BACKGROUND: A sarcoid reaction is a phenomenon characterized by histologically proven granulomatous lesions without evidence of sarcoidosis. This pathology is a benign tumor itself, but several reports have described sarcoid reactions accompanying malignant tumors. Sarcoid reactions occur in various cancers, such as skin, lung, ovary, stomach, and breast cancers. However, only a few published reports have described sarcoid reactions in patients with colorectal cancer. CASE PRESENTATION: A 76-year-old woman underwent laparoscopic sigmoidectomy for sigmoid colon cancer...

Tuberous sclerosis complex (TSC) is a genetic multi-organ disorder characterized by the development of neoplastic lesions in kidney, lung, brain, heart and skin. It is caused by an inactivating mutation in tumor suppressor genes coding the TSC1/TSC2 complex, resulting in hyperactivation of mTOR- and Raf/MEK/MAPK-dependent signaling that stimulates tumor cell proliferation and metastasis. Despite its oncogenic effect, cells with TSC deficiency were more sensitive to oxidative stress and dependent on mitochondrial metabolism, providing a rationale for a new therapeutic approach...

Metastasis of lung cancer to soft tissue is rare and patient outcomes are generally poor. There are no reports describing soft tissue metastasis in lung squamous cell carcinoma (SCC), in which gefitinib treatment was effective not only for the primary tumor but also the metastatic lesion. A 61-year-old Asian woman presented to our facility with pain and a mass in the brachium. An additional tumor was identified in the lung. As we suspected soft tissue metastasis of lung cancer, an incisional biopsy was performed, yielding a diagnosis of SCC...

Chordoma is a rare primary bone malignancy of notochord origin, representing 1-4% of malignant bone tumors. Typically, chordomas follow a slow progressive course with aggressive local extension, multiple recurrences, and metastases. Of particular interest to this case, cutaneous metastasis is exceedingly rare. Diagnosis of this entity can be a challenge due to the rarity of chordoma, as well as the infrequent presentation of distant cutaneous metastasis and non-specific clinical skin findings. We report a case of a 61-year-old male with a history of sacral chordoma treated by wide local excision 8 years prior to presentation developed a nodule on his scalp for 6 weeks...

Erlotinib is one of the most widely used tyrosine kinase inhibitor targeting human epidermal growth factor receptor. Since its introduction, it has revolutionized the treatment of advanced non-small cell lung cancer. Skin rashes and diarrhea are the most often reported side effects of erlotinib however it is also associated with interstitial pneumonitis or interstitial lung disease, which often turns out to be fatal complication of using this medicine. Though reported scarcely in the western world, the association of interstitial lung disease with epidermal growth factor receptor has attracted a lot of attention in the recent times...

Dermatofibrosarcoma protuberans (DFSP) is a rare disease of dermal fibroblastic origin that accounts for less than 5% of all soft tissue sarcomas in adults. DFSP grows slowly and is an asymptomatic lesion at the initial diagnosis. Herein, we report a case of multiple pedunculated nodules as a variant of DFSP. A 47-year-old man presented with a 7-month history of multiple well-circumscribed, firm, pedunculated nodules on the inguinal area. Histopathologic examination results showed densely packed uniform spindle cells with a storiform and cartwheel pattern, and positivity for CD34...

Breast cancer is the most common cancer among women and ranks second in cancer deaths worldwide. Breast cancer can metastasize to the skin but rarely, cutaneous metastases may be the first indication of the cancer. Skin metastases of breast cancer are usually found on the chest and close to the point of the mastectomy. We present the rare clinical entity of a breast cancer which was first diagnosed due to the skin metastasis away from the breast tumor. This is a rare case because the skin lesions usually appear simultaneously or secondary...

PURPOSE: Skin metastasis is one of the most frequent metastases in breast cancer patients. Patients with malignant wounds experience numerous symptoms, including serious wound pain. However, the features of pain related to malignant wounds have not been investigated. Nurses can experience a dilemma when treating these patients due to a lack of knowledge of the pain. The aims of this study were to examine the quality and intensity of malignant wound pain and to determine the association between wound status and pain in the patients with malignant wounds...

The presence of malignancy is considered a contraindication to the use of negative pressure wound therapy (NPWT) because of concerns that it may promote tumourigenesis and expedite metastasis. This notion is extrapolated from studies evaluating NPWT in normal tissues. Despite the absence of direct evidence, the use of this technology in malignant wounds is widely considered a contraindication. We present the case of a patient with treatment-resistant metastatic colon cancer, who developed a chronic abdominal wound with positive margins...

Tumor heterogeneity has been suggested based on clinical and pathological findings. Several clinical findings can be explained by tumor evolution during progression and metastasis. We herein report a case of metastatic breast cancer indicated tumor heterogeneity by clinical findings and a genomic analysis. A 64-year-old woman with advanced breast cancer was treated with primary chemotherapy, to which primary tumor responded. After a 6 month treatment pause, lung, liver, and skin metastases developed and her serum tumor markers were elevated...

BACKGROUND: Although cervix carcinoma is one of the most common malignancies in women, hematogenous metastases are relatively not common. Cutaneous metastases, in particular, are unusual even at an advanced stage of disease. Their presence is a predictor of poor prognosis. CASE PRESENTATION: Case 1: A 63-year-old postmenopausal Moroccan woman was diagnosed as having cervical squamous cell carcinoma. She was treated with radical concurrent chemotherapy and radiation therapy followed by low-dose brachytherapy...

BACKGROUND: Isolated locoregional recurrences (ILRRs) of breast cancer confer a significant risk for the development of distant metastasis. Management practices and second ILRR events in the Chemotherapy as Adjuvant for LOcally Recurrent breast cancer (CALOR) trial were investigated. METHODS: In this study, 162 patients with ILRR were randomly assigned to receive postoperative chemotherapy or no chemotherapy. Descriptive statistics characterize outcomes according to local therapy and the influence of hormone receptor status on subsequent recurrences...
