Abstract
CASE REPORT: We report a case of 70-year-old male from Sicily, who presented with a bilateral eyelid mass involving the tarsal conjunctiva, found to be Kaposi's sarcoma on histologic examination. Cutaneous and pulmonary Kaposi's sarcoma involvement was documented. The patient had no prior diagnosis of human immunodeficiency virus infection. This case was managed successfully after the completion of five cycles of chemotherapy with liposomal doxorubicin, and his eyelid, skin and pulmonary lesions disappeared.
CONCLUSIONS: Location in the eyelid is a possible, though rare, initial solitary manifestation of Kaposi's sarcoma in elderly HIV-negative patients. Liposomal doxorubicin is a safe and effective treatment.

Paleopathological evidence of paranasal lesions: Two cases of frontal sinus osteomata from Imperial Rome.

Abstract
The archaeological excavations carried out in 1999 in the Collatina necropolis of the Roman Imperial Age (1st-3rd centuries AD) (Rome, Italy) discovered the skeletal remains of two adult males with evidence of paranasal lesions. Both individuals showed postmortem damage in the frontal bone, through which it was possible to macroscopically detect an oblong new bone formation. In both specimens, radiological examination of the defects' morphology showed new pediculated-based bone formations. Radiology also confirmed the presence of benign osseous masses arising from the right frontal sinus and interpreted as osteomata. Their dimensions did not exceed 10 mm, so that mechanical complications and compression of the adjacent structures could be ruled out. The osteomata of paranasal sinuses are rarely reported in paleopathology, since they can be discovered only incidental to bone breakage or radiography. Hence, the evaluation of their occurrence in past populations represents an important challenge. The two cases presented here show direct and rare evidence of frontal sinus osteomata dating back to the Roman Imperial Age.

Lingual Fibrolipoma - A rare clinicopathological entity.

S Afr J Surg. 2017 Jun;55(2):36

Authors: Mungul S, Maharaj S, Masege SD

Abstract
Lipoma is a relatively common benign tumour occurring at sites of the body which are rich in adipose tissue. Due to sparsity of adipose tissue within the oral cavity, lipoma rarely presents in this region. Fibrolipoma of the tongue is a rare lesion. There are only 14 cases reported in the literature. An 85-year-old patient presented with a painless mass on the tongue interfering with eating. There were no risk factors for malignancy and no family history of malignant diseases. Although intraoperatively the lesion was locally infiltrative, histopathology revealed a rare benign fibrolipoma. Mainstay of treatment is surgical excision, but the lesion may pose a dilemma for Surgeons as difficulties associated with removal, due to the fibrous and adherent nature of the growth to surrounding tissue, may be mistaken for a cancerous growth.

Suspected Lateral Periodontal Cyst Presenting Concurrently with Canine Acanthomatous Ameloblastoma in a 2-Year-Old Standard Poodle.

J Vet Dent. 2017 09;34(3):141-147

Abstract
Lateral periodontal cysts (LPCs) are odontogenic epithelial cysts composed of nonkeratinized epithelial cells that are in the category of developmental cysts, rather than inflammatory cysts. Lateral periodontal cysts are rare both in people and domestic animals; they are associated with vital teeth and located lateral to a tooth root. Lateral periodontal cysts are typically asymptomatic lesions that are characterized radiographically as a unilocular lucency with well-defined corticated borders. Canine acanthomatous ameloblastoma (CAA) is the most common odontogenic neoplasm in dogs and rarely presents as a cystic lesion. This case report describes the diagnosis and treatment of a cyst that occurred as a swelling apical to a gingival mass that was diagnosed histologically as CAA. Surgical management by conservative gingivectomy, cyst enucleation, and bone grafting was an effective treatment in this patient.
