BACKGROUND Ocular adnexal IgG4-related sclerosing disease (IgG4-SD) has been categorized as a novel disease entity. It is characterized by stromal sclerosis and an infiltration of mass-forming lymphoplasmic cells containing many IgG4-positive plasma cells. Although ocular adnexal tissue involvement has been increasingly reported, a focal nodular sub-brow mass is not typical in an IgG4-SD presen...

Further noncontrast CT scan was performed, which revealed well-defined, well-circumscribed smooth marginated solid cystic lesion in superficial and deep lobes of left parotid gland, predominantly in posteroinferior part of gland, medially the lesion extends into stylomandibular tunnel (Figure 1). On postcontrast CT, irregular nodular enhancement of solid part was noted and in close relation to ...

Abstract A 14-year-old boy presented with left preauricular painless swelling of 10 months' duration. Local examination revealed a 3 × 2-cm, firm, nodular, nonmobile mass in the area, just front tragus. Fine needle aspiration yielded paucicellular smears comprising singly scattered histiocyte/myofibroblast-like spindle cells and occasional giant cells. It was reported as benign mesenchymal lesi...

A malignant melanoma is an abnormal proliferation of pigmented cells in the body. Half these tumors have BRAF mutations, with a worse response to treatment. We present case 58-year-old male nodular lesion on right calf and inguinal lymphadenopathy.

Focal nodular hyperplasia is a benign liver lesion incidentally discovered with increasing frequency because of the proliferation of imaging studies. Radiographic characterization can diagnose this pathologic lesion and nonoperative therapy is the standard of care. However, surgical resection may be required for diagnostic reasons or symptomatic patients. Depending on the anatomic location of t...

Leiomyomas are the most common benign mesenchymal uterine tumour. The vast majority of these have a typical macroscopic and histological appearance. Approximately 10% leiomyomas subtyped due to unusual or microscopic differences. Cotyledonoid dissecting considered one rarer subtypes leiomyoma, with distinct features that can be worrying for malignancy require correlation diagnosis. Whilst will ...

Abstract A 1.5-year-old male Iberian lynx born in captivity presented with a 2.2 cm exophytic nodular alopecic mass at the left tarsus medial aspect, before being released into wild. The lesion had keratinised material protruding through 1.2 pore, forming cutaneous horn. Histopathology revealed cystic dermo-epidermal lined by psoriasiform hyperplasia of epithelium, thicker base cyst, together a...

Ligneous conjunctivitis is a type of chronic characterized by the presence pseudomembranes on conjunctival surface. It can present as part multisystem disease with involvement other mucous membranes. A 1-year-old girl presented features conjunctivitis. Local examination revealed thick exudates in left tarsal conjunctiva, which was diagnosed an ulcer pseudomembrane and sterile culture. The patie...

Pulmonary cavitary lesions with pneumothorax are very common in chest imaging and usually pose diagnostic challenge to clinicians Pneumothorax a lesion is rare occurrence primary metastatic lung cancer. A 40-year-old male presented cough whitish expectoration, right loin pain, loss of weight appetite for 3 months difficulty breathing 2 days. Chest x-ray was suggestive right-side bilateral nodul...

Intracranial epidermoid cysts are usually located in the paramedian regions with characteristic imaging features. Intracystic hemorrhage is rarely reported with most in the cerebellopontine angle area. We described a case of hemorrhagic epidermoid cyst in cerebellar vermis. The patient was a 21-year-old male presenting with a first episode of convulsive seizure attack as the initial and sole sy...
