Cysts of accessory lacrimal gland are rare. They are generally retension cysts that result from obstruction of the excretory duct and are found between the palpebral conjunctiva and the levator aponeurosis. We experienced three cases of subconjunctival cyst in the upper fornix. Histopathological examination showed the cysts lined by two layers and occasionally one layer of epithelium. These cysts seem to be originated from Krause's gland, considering their anatomical location and histopathological findings.

The combination of dacryocystography and computed tomography have been called as computed tomographic dacryocystography. The authors carried out computed tomographic dacryocystography using water soluble contrast media, Rayvist(R), in two patients with a mass around the lacrimal fossa. This radiologic technique demonstrated that the lacrimal system was not invaded by the tumor and was helpful in planning the surgical approach. The results of excisional biopsy of the mass revealed an epidermoid cyst in both cases.

Angiomyolipoma(AML) of the liver is a rare benign tumor; about 60 cases, almost solitary, have been reported. We present here a extremely rare case of multiple AML in the liver diagnosed by fine needle aspiration cytology (FNAC). Two large masses were found in a 51 year-old woman complaining of abdominal discomfort by computed tomography and several smaller masses are scattered in the liver. FNAC was performed, showing bundles of spindle shaped smooth muscle cells intermingled with mature fat cells. FNAC may be a valuable method for definitive diagnosis of hepatic AML. The diagnosis was further confirmed by histologic examination with immunohistochemical studies.

An one-day-old female patient was admitted due to marked abdominal distension, cyanosis, right upper quadrant mass, and respiratory failure since birth. We applied ventilator and supportive care immediatly. However, 4 days later, she was dead due to respiratory failure and hemorragic complication. The radiographic finding showed a huge intra-abdominal mass anterior to the intestine. Autopsy findings showed a huge single cystic tumor in the right lobe of the liver. The cysts were filled with sanguinous fluid. There wasn't any signs of necrosis or calcification. Microscopically, the tumor was well demarcated from the adjacent hepatic parenchyma. It consists of connective tissue with dilated lymphatics, vessels, and bile ducts.

Leber's hereditary optic neuropathy (LHON) is an important cause of bilateral optic neuropathy in youth and occasionally associated with other neurological abnormalities (Leber's plus). The authors recently found out one family of LHON and another patient of Leber's plus with mitochondrial DNA (mtDNA) 11778 mutation. The presence of a point mutation of mtDNA was investigated by restriction length fragment polymorphism. Among 14 patients who had mtDNA 11778 mutation in the family, only two men had bilateral optic neuropathy. The other was a man of optic neuropathy with myelopathy. The age at onset of visual loss ranged from 14 to 25 (average 19.7). The time delay between involvement of the two eyes was I to 3 months Central visual field defect was observed in each of all affected eyes and worse in the earlier affected. The brain MRI and CSF studies revealed no abnormality. This study showed that the clinical manifestations and genealogical features of LHON in our patients are similar to those of previously reported cases in other countries.

Grover disease (GD), also referred to as transient or persistent acantholytic dermatosis, is an acquired pruritic papular or papulovesicular eruption characterized histopathologically by focal acantholysis and dyskeratosis. Because GD resembles several generalized papular diseases, the diagnosis of GD is a clinical challenge, particularly when dermatologists meet patients without papular eruptions. We experienced two elderly men showing eczematoid plaques with severe pruritus on their backs. Histopathological examinations revealed a focal acantholysis, spongiosis, and dyskeratosis, a pattern consistent with GD. We report two cases of GD with clinical features of nonspecific eczematous dermatosis.

Melanosis ilei is an extremely rare condition in which black pigment, consisted of aluminum, magnesium, or silicon, accumulate in the terminal ileal mucosa. Medical treatment with charcoal enhances the neutralization of the toxic material and elimination of many drugs. In addition, it has been used as a traditional remedy in some oriental countries to relieve chronic diarrhea, abdominal pain, or acute enterocolitis, which is made up carbon, oxygen, aluminum, magnesium, silicon, calcium, and palladium. Two patients taking the charcoal for a long time underwent a colonoscopy to evaluate chronic diarrhea or abdominal pain. The colonoscopy revealed a normal colonic mucosa and multiple geographic black-pigmented mucosal changes at the terminal ileum. Therefore, it was assumed that melanosis ilei can develop in patients with long-standing charcoal ingestion. To the best of our knowledge, this is the first case of melanosis ilei associated with the ingestion of charcoal.

Photodynamic therapy is a promising modality for the palliation of advanced upper gastrointestinal cancer and for the eradication of early neoplastic and pre-neoplastic lesions. It is based on the combination of a photosensitizer that is selectively localized in the target tissue and illumination of the lesion with visible light, resulting in photodamage and subsequent cell death. For early esophageal cancer, esophagectomy has been a standard modality of curative intent. However, accumulated data supports the possibility of PDT replacing surgery as a curative modality. We experienced a case of early esophageal cancer that recurred after esophagectomy. The patient was successfully treated with photodynamic therapy using porfimer sodium as a photosensitizer.
