Kaposi's sarcoma (KS) is a multicentric vascular neoplasm, with cutaneous and extracutaneous involvement. Different clinical and epidemiological variants have been identified. The classic form is manifested mainly in elderly men with indolent and long-term evolution, with lesions localized primarily in the lower extremities. We present two cases of classic Kaposi's sarcoma (CKS) in two female p...

The concept of angiogenesis and consecutive stages of the neovascularization processes under physiological and pathological conditions have been described. Angiogenesis is regulated by the different mechanisms which are in dynamic balance. The regulating components of these processes are the stimulating and inhibiting factors, the mediators of these reactions under influence of the host cell-tu...

Dermatoscopic features of spiradenoma—a benign adnexal neoplasm—have not been described. We present a case of spiradenoma occurring on the occipital scalp (Figure 1A, 1B) that showed a structureless pattern and blue clods on dermatoscopy. The vascular pattern of serpentine, branched vessels (Figure 2) in combination with blue clods suggest a basal cell carcinoma (BCC) [1]. However, the blue clo...

Primary testicular carcinoid tumor, occupying 0.23% of testicular neoplasm, is a rare and indolent neoplasm with the potential for distant metastasis. We present two cases of primary pure carcinoid tumor of the testis. Both patients were 36 years old. Physical examination revealed testicular mass with and without tenderness. The preoperative serum levels of beta-human chorionic gonadotropin and...

results: among 11 patients who underwent surgery consisted of eight males and three females. their metastasis originated from testis tumors (n = 5), renal cell carcinoma (rcc; n = 4), bladder tumor (n = 1), and prostate cancer (n = 1). their mean age was 41.27 years (range, 21-67). the mean age of the patients with rcc and testis tumor at the time of diagnosing metastasis was 54 and 24.8 years,...

Background Trauma to the foot and distal phalanx are common presenting complaints. In contrast, neoplasia of or hoof region is rarely reported. Within foot, keratomas most frequently reported neoplasm. The gross radiographic appearance well documented; however, this less established for other neoplasms capsule. Objective This paper presents four cases which had clinical similarities keratomas; ...

The nose is an uncommon site for head and neck paraganglioma. The diagnosis is seldom established pre-operatively; its rarity, infrequent functionality and often benign biologic outcome underlie this fact. We present one such case in a 60-year-old man who presented with right nasal obstruction and episodic epistaxis. Rhinoscopy revealed a fleshy polypoid mass arising from the anterior cartilagi...

Background. Classification of hemangiopericytoma (HPC) has evolved to a mesenchymal, nonmeningothelial grade two or three neoplasm according to the World Health Organization; however its blood supply has always been defined by dual origin, pial and dural contribution. Case Description. We present the case of a patient with an intracranial HPC with only pial vascular supply. Angiography confirme...

Hemangioblastomas are rare vascular tumors most often found in the posterior fossa and cervical spinal cord and commonly associated with von Hippel-Lindau Disease. We report a case of sporadic hemangioblastoma in a patient without von Hippel-Lindau Disease. Imaging characteristics included a solid, suprasellar mass that was homogeneously enhancing. These findings most resembled a pituicytoma or...
