Primary Epithelioid Sarcoma of Lacrimal Gland and Primary Renal Cell Carcinoma with whole Exome Sequencing: a Case Report
The 31-year old male patient with primary orbital epithelioid sarcoma of lacrimal gland in combination with primary renal cell carcinoma is being presented. Epithelioid sarcoma is a rare high-grade aggressive malignant soft tissue tumor. Until now, all reported cases were localized in the orbit, but to our knowledge, this is the first case primary localized in the
lacrimal gland.
Dermatofibrosarcoma Protuberans of Abdominal Wall: A Case Report
Dermatofibrosacroma protuberans of abdominal wall is very rare. Surgery is treatment
HIV-Associated Oral Kaposi Sarcoma: Case Report and Literature Review
Kaposi sarcoma (KS) is an angioproliferative polymorfic disorder that might be associated with human immunodeficiency virus (HIV) infection. In this clinical form, oral manifestation is particularly common and, sometimes, the first manifestation of the retroviral infection. In those cases, KS diagnosis is fundamental as the treatment is based in HIV infection control through an advisable multidisciplinary approach.
A Clinical Case Study of Paratesticular Rhabdomyosarcoma of Young Adult
Para-testicular rhabdomyosarcoma (RPT) is a rare tumor of children and adolescents. The diagnosis is made by the anatomopathological study. The treatment must be multimodal and involves surgery, chemotherapy and radiotherapy. We report the case of a 19-year-old adolescent in our department for an embryonic-type para-testicular rhabdomyosarcoma. Our aim is to expose a rare and unknown case that may be life-threatening. We would like to emphasize on the fact that paratesticular rhabdomyosarcoma need to be brought
up in front of a tissular process expanding in the scrotum with normal testicules.
Immunohistochemical Localization of LH Receptors in Canine Splenic Hemangiosarcoma
Gonad removal has been implicated as a risk factor for the development of canine hemangiosarcoma. With gonad removal, there is a loss of negative feedback to the anterior pituitary, resulting in persistently elevated concentrations of luteinizing hormone (LH). LH receptors can be found in gonadal and extragonadal tissues, including the bladder and skin. The aim of this study was to investigate if LH receptors were expressed in canine splenic hemangiosarcoma. Splenic tumor samples submitted to the Oregon State Veterinary Diagnostic Laboratory from referring veterinarians were with routine immunohistochemical methods. In addition, survival time following hemangiosarcoma diagnosis was obtained from the referring veterinarians. Five of the eight splenic hemangiosarcomas (62.5 %) were positive for LH receptor expression. LH receptor cellular localization in splenic hemangiosarcoma was cytoplasmic and granular, similar to the positive control canine skin sections (Figure 1C). There was no positive staining in the negative controls. LH receptor is expressed in a proportion of HSAs but further study need to be done to assess the significance of this finding.
Malignant Soft Tissue Sarcoma at the Site of Corticosteroid Injection in a Dog
An 11-year-old spayed female dog was presented for a large mass on the left proximal pelvic limb. The mass appeared three months prior to presentation in the location of a previous corticosteroid injection, Kenalog (0.05 mg/kg triamcinolone, CAS# 76-25-5). No vaccinations or injections had been previously given in this area. The mass spanned from the left stifle to the coxofemoral joint and was firm, circular, non-moveable, and diffusely mixed within the musculature of the thigh. A left external complete hemipelvectomy was performed. Histopathology was consistent with a Grade III fibromyxosarcoma. The dog died naturally at home five months after surgery. This is the first account of association of a corticosteroid injection with formation of a fibromyxosarcoma in a dog.
Primary Osteosarcoma of the Nasal Fossa: An Exceptional Presentation
Sarcomas of the head and neck are very rare accounting for approximately 1% of all head and neck neoplasms. Primary osteosarcomas of the nasal cavity are less than 0.5% of the osteosarcomas occur in this location. Because of the rarity of this presentation, we report a case of a 54 year old male with primary osteosarcoma arising de novo from the nasal cavity, presented with left epistaxis and bilateral nasal obstruction.
A Rare Case Report of Primary Pure Pleomorphic Liposarcoma of Breast with Cytological and Histopathological Findings
Sarcomas of a breast are rare tumors. Primary mammary liposarcomas are rarer still. The peak incidence of breast liposarcomas in adults occur between 4th and 6th decades. We report a case of primary breast pleomorphic liposarcoma in a 70 years old female patient. FNAC of the tumor was non-specific. However, histopathological along with immunohistochemical studies clinched the diagnosis.
Metastatic Leiomyosarcoma of the Inferior Vena Cava Presenting with a Hepatic Mass
A case report of a 72-year-old female patient presenting with right-sided abdominal pain and back pain, on which initial abdominal ultrasound revealed a hepatic mass.
An Early Description of Carcinosarcoma in 1883
By 1804, John Abernethy was aware of the existence of a tumor which he called carcinomatous sarcoma. In this context, this paper presentshow, in 1883, David Finlay fully documented a case whose data were indicative of the formation of carcinosarcoma in a woman sufferingfrom fibroids.
Sudden Death Due to Sarcoma: An Unusual Case and Literature Review
Sudden death has varied causes, and autopsy is usually required to determine cause of death. Sarcoma involvement is very infrequent, and detailed pathological evaluation is needed for correct diagnosis.
Inflammatory Myofibroblastic Tumor of Proximal Urethra in a Pregnant Female: A Unique Case Report
Inflammatory Myofibroblastic tumour (IMT) is a rare spindle tumour that mimics malignant processes. It can affect any part of the body, but rarely occurs in the genitourinary tract. We report a case of urethral IMT in a 31-year-old pregnant female of 18 weeks gestational age.
Review on Pharmacological Activities of the Peptides from Scorpion Buthus Martensii Karsch
In China, the scorpion Buthus martensii Karsch is used as functional food and medicinal materials. The scorpion, scorpion venoms and their extracts are effective in treating a variety of nervous system diseases such as epilepsy, apoplexy pains and facial paralysis.
m6a RNA Methylation: The Implications for Health and Disease
The recent resurgence of interest in m6A has been spurred by some intriguing findings detailing the effects and dynamics of this epigenetic modification. The m6A modification is a highly reactive and fluid modification which can respond rapidly to a broad variety of stimuli, and translate these signals into cellular activity. The little information that has been established on its functional capacity has opened up many new avenues of research and has tremendous implications for several fields of study.
Juvenile Ossifying Fibroma - WHO Type
Juvenile ossifying fibroma is an uncommon clinical entity, its aggressive local behaviour and high recurrence rate mean that it is important
to make an early diagnosis, apply the appropriate treatment and, especially, follow the patient up over the long term. In the
current article we report a case of juvenile ossifying fibroma-WHO type in 12yr old patient which was clinical and histopathologically
challenging as it was asymptomatic and at an unusual location.
