We report a patient with carcinomatous meningitis secondary to known transitional cell carcinoma of the bladder. The patient presented with multiple focal neurological signs and symptoms. Diagnosis was suggested by magnetic resonance imaging and confirmed by analysis of the cerebrospinal fluid. He received whole brain radiotherapy despite a poor prognosis. To our knowledge, this is only the fifth reported case of neoplastic meningitis due to bladder cancer with confirmatory imaging and cytology and only the fourth reported case that presented with cranial nerve involvement.

Frozen section is a valuable tool that is often underutilized in the setting of in-patient dermatology. Traditionally, frozen section has been used in dermatology to diagnose toxic epidermal necrolysis, with some additional utility in staphylococcal scalded skin syndrome in the new born period. We report a newborn female with ruptured bullae on the face, chest, back and extremities with a clinical differential diagnosis that included staphylococcal scalded skin, bullous congenital ichthyosiform erythroderma/epidermolytic hyperkeratosis and epidermolysis bullosa. A thin detached skin sample ('jelly-roll') taken from a ruptured bulla on the abdomen was prepared for frozen section analysis. Characteristic findings of epidermolytic hyperkeratosis were seen which included hyperkeratosis with granular layer degeneration, vacuolization and eosinophilic globules. The 'jelly-roll' technique can be used for quick diagnosis with minimal trauma to the patient. Epidermolytic hyperkeratosis was subsequently confirmed by a biopsy fixed in formalin and by genetic testing. A novel missense mutation in KRT1 (I479N) was identified. Herein, we discuss the use of the frozen section 'jelly roll' technique for rapid diagnosis in a case of bullous congenital ichthyosis erythroderma/epidermolytic hyperkeratosis.
