Nodular Hidradenoma

Nodular hidradenoma (NH) is a benign adnexal tumor that arises from either eccrine or apocrine sweat glands. NH can originate from any cutaneous site, but the most common sites are the head and anterior surface of the trunk, with very rare cases in the extremities. Long-standing NH has been reported to undergo malignant transformation to malignant NH (MNH); however, its occurrence in the lower leg is extremely rare with only one other case reported to date. In this report, we present a rare case of MNH occurring in the lower leg which was resected with the intent to make a diagnosis. At the final follow-up after 11 months, no local recurrence or metastasis has been observed.

Background: Kissing nevus is a congenital nevus in adjacent parts of the eyelids. Malignant transformation of kissing or divided nevi of the eyelids is rarely described. Objective: To report a very rare case of malignant transformation of kissing nevus with ocular and extraocular spread. Case: A 57- year- old man with 6/6 visual acuity in both eyes presented with a kissing nevus present since birth in right upper and lower eyelids which had a slow growth phase. The upper lid in the area of the nevus was thickened with a 20x12x15 mm black pigmented crusted hemorrhagic nodular lesions. The lower lid had a 6 mm black pigmented ulcerated lesion over the pre-existing nevus in the lateral third of the lid with full thickness infiltration. Another 5x4 mm pigmented lesion over the lower medial lid margin with a thickness of about 3 mm extended to the conjunctival side of the lower lid. Right sided pre-auricular and submaxillary nodes were palpable. A biopsy of tissue samples from the eyelid and pre-auricular nodes were consistent with malignant melanoma.Conclusion: Malignant transformation of kissing nevus is rare. It can spread to the conjunctiva, pre-auricular and sub-mandibular lymphnodes.DOI: http://dx.doi.org/10.3126/nepjoph.v4i2.6555 Nepal J Ophthalmol 2012; 4 (2): 329-332

Surgical Condition

ABSTRACT Gastric diverticulum is an extremely rare surgical condition. Most patients are asymptomatic, hence, the diagnosis is more often incidentally made than otherwise. They are usually congenital, solitary and are located on posterior wall and the lesser curvature. Patients presenting are usually between 20 and 50 years of age. Gastric diverticula harbor risk of the same complications as diverticula elsewhere in the gastrointestinal (GI) tract, such as bleeding, diverticulitis, obstruction, perforation, ectopic tissue, and malignant transformation. We present a rare case of a 48-year-old female with gastric diverticula in the posterior wall of fundus of stomach with gallstone disease which was managed surgically and a brief review of literature.

Schneiderian Papilloma

We report a rare case of a schneiderian papilloma of the nasopharynx. Because this tumor is locally invasive, has a tendency to recur, and can undergo malignant transformation, it should be completely excised. It is possible to completely remove such a tumor in a minimally invasive way by using a combination of transnasal and transoral approaches and high-resolution angled endoscopes and other suitably designed instruments.

Rare Benign Tumor

ABSTRACTNeurofibromas (NF) are benign tumors of neural origin, of which roughly 90% appear as solitary lesions. They are classified into cutaneous, subcutaneous, and plexiform subtypes. Plexiform neurofibromas are the least common variant and usually are pathognomonic for NF I. Here, we present a very rare case of isolated plexiform neurofibroma with a painless enlarging mass of the tongue of an 11-year-old girl. This rare benign tumor has the potential for malignant transformation, and the diagnosis was difficult owing to the patient's age and to the insidious clinical presentation. The present case is a diffuse isolated plexiform neurofibroma of the tongue that was not associated with neurofibromatosis that was treated with intraoral surgery.
