Cowden syndrome, also known as multiple hamartoma syndrome is a rare autosomal dominant disorder characterized by multiple hamartomatous tumors of ectodermal, mesodermal and endodermal origin. A 47-year-old woman had a skin-colored plaque on the left foot. She had total abdominal hysterectomy due to uterine leiomyoma at the age of 35, and had modified radical mastectomy due to right breast cancer at 38. Thyroid adenoma was diagnosed at age 46. Physical examinations revealed macrocephaly, multipl

A 23-year-old man had recurrent erythematous purpuric patches in a transverse-linear arrangement on his back and arms. One week prior to a recent episode, he took acetaminophen for 3 days. Four months earlier, he developed the same purpuric lesions at/around the same anatomical site when he took acetaminophen for pain-relief. A biopsy specimen showed capillaritis and extravasation of erythrocytes in the papillary dermis. A provocation test with acetaminophen confirmed these lesions as drug-induc

A 23‐year‐old woman (gravida 1, para 0) in her 34th week of pregnancy had urticarial erythema on the legs for a period of 2 weeks. The initial eruptions of erythematous papules, plaques, and urticarial lesions were noted on the calves, at the site of striae distensae. The number of erythematous le‐sions had increased during the last 10 days to cover most of the preexisting sites of striae distensae on the lower legs and thighs, with several satellite lesions (Fig. 1). Individual lesions on the l

A case of erythromelanosis follicularis faciei et colli is described which showed deposition of calcium in the lesional skin on the face.

Cells regulate their intracellular mRNA levels by using specific ribonucleases. Oligoribonuclease (ORN) is a 3'-5' exoribonuclease for small RNA molecules, important in RNA degradation and re-utilisation. However, there is no structural information on the ligand-binding form of ORNs. In this study, the crystal structures of oligoribonuclease from Colwellia psychrerythraea strain 34H (CpsORN) were determined in four different forms: unliganded-structure, thymidine 5'-monophosphate p-nitrophenyl e

A case of pemphigus foliaceus which initially developed at sites of preexisting psoriasis and a case of pemphigus erythematosus that developed on the lesions of photosensitive erythemas are described. Inflammatory dermatoses can be considered to be local factors which facilitate the autoimmune response of pemphigus, which in turn may induce blistering cutaneous lesions in subclinical patients with autoantibodies.

A 44-year-old woman presented with blisters on her face of 1-month's duration. A biopsy showed a subepidermal bulla with a dermal infiltrate of inflammatory cells and thick linear deposits of immunoreactants along the dermo-epidermal junction. Using Western immunoblots, the patient's IgG antibody was found to recognize type VII procollagen. Moderate doses of oral prednisolone resulted in a complete remission, without a recurrence for more than 3 years.

Neuronal ceroid lipofuscinosis, which is also known as Batten-Bielschowsky disease, is a group of neuro degenerative disorders, associated with various progressive symptoms including seizures, dementia, visual loss and cerebral atrophy. We experienced a case of late infantile neuronal ceroid lipofuscinosis in a 6-year-old boy who had progressive myoclonic seizures, ataxia, rapid psychomotor deterioration and visual loss. Photic stimulation at 2 to 5 Hz elicited a discrete spike and wave discharg

Schwannomas of the sinonasal tract are rare, accounting for <4% of head and neck schwannomas. We report the case of a 61-year-old male who presented with unilateral nasal symptoms. Examination and imaging revealed a unilateral polyp at the level of the middle turbinate, with an initial biopsy suggestive of an inflammatory polyp. Due to the persistence of the patient's symptoms and his polyp despite medical therapy, endoscopic nasal polypectomy was performed. The histology surprisingly showed a s
