Pityriasis rotunda is a rare disease characterized by round to oval, sharply defined, hypopigmented or hyperpigmented, scaly patches of variable number and size located trunk and extremity. The etiology is unknown but it has been associated with a variety of systemic illnesses, such as tuberculosis, malnutrition and malignancy. The first case was a 28-year-old male who presented with a 2-year history of multiple round shaped hyperpigmented patches on the trunk. The second-case was a 38-year-old female who presented with a 2-month history of circular, sharply defined multiple patches with ichthyosiform scaling on the trunk. Both patients had no systemic disease or familial history. We experienced 2 cases of pityriasis rotunda on the trunk without underlying systemic illnesses or familial association.

Most cases of delayed skin reactions attributed to non-ionic iodinated contrast media, reported to date, have been maculopapular rash, which frequently occurs on the trunk and proximal region of the extremities. Only few cases of fixed drug eruption caused by non-ionic iodinated contrast media have been reported. A 48-year-old man developed multiple sharply marginated, hyperpigmented, oval patches on the trunk and extremities after receiving iodixanol (Visipaque(R), GE healthcare, USA). The patch test was carried out with a panel of the available iodinated non-ionic contrast media, but did not induce a positive reaction to any of the tested contrast media. The provocation test was carried out with iodixanol as 1/10 of the amount administered during the procedure that caused the reaction. On the following morning, the lesions increased in size and number. We report a case of iodixanol-induced fixed drug eruption, diagnosed by a systemic provocation test.

Aplasia cutis congenita is a rare congenital condition, characterized by localized absence of epidermis, dermis, and in some cases, subcutaneous tissues. About 80% of the patients with aplasia cutis congenita have involvement of the scalp. Aplasia cutis congenita, not involving the scalp, appears to be linear lesions with a symmetrical pattern of distribution on the trunk and limbs. Most reported cases are sporadic, but a few cases have been reported to have familial occurrence. There is no unifying theory for the pathogenesis and etiology. Herein, we report a 1-day-old female infant and her 4-year-old sister with unilateral aplasia cutis congenita on their legs. No similar conditions and other associated congenital anomalies were found in their family. There was no sign of teratogenic causes, such as intrauterine infections, drugs or chemical agents.
