Eponyms are used almost daily in the clinical practice of dermatology. And yet, information about the person behind the eponyms is difficult to find. Indeed, who is? What is this person’s nationality? Is this person alive or dead? How can one find the paper in which this person first described the disease? Eponyms are used to describe not only disease, but also clinical signs, surgical procedures, staining techniques, pharmacological formulations, and even pieces of equipment. In this article we present the symptoms starting with (K) and other. The symptoms and their synonyms, and those who have described this symptom or phenomenon.

Soft tissue chondroma (STC), also known as extraskeletal chondroma or chondroma of soft parts is a benign cartilaginous tumor which arise de novo from soft tissue. Also, it is an extremely rare entity predominantly involving extremities, especially fingers. A 26 year old male presented with 3 year history of swelling in left index finger. On local examination a hard 2 × 2 cm swelling was seen over the volar aspect of left 2nd proximal phalanx. Swelling was mobile on contraction of tendons. X-ray showed a soft tissue shadow on volar aspect of left second proximal phalanx. Histopathology showed a well encapsulated, hypo cellular nodule composed of benign chondrocytes surrounded by hyaline chondroid matrix. Nuclear pleomorphism, mitosis or necrosis was not seen. Based on radiological and histopathological findings a diagnosis of STC was made. STC should be considered in patients with slow growing, soft tissue masses.

Congenital self-healing reticulohistiocytosis (CSHRH) is a benign type of Langerhans cell histiocytosis (LCH) also known as Hashimoto-Pritzker disease. Clinically it presents with skin lesions at birth or in neonatal period, usually without any systemic involvement. Lesions often heal spontaneously in period of weeks to months. We report a case of CSHRH presenting with skin lesions at birth, describing need to make an early diagnosis and to have a multidisciplinary approach with regular follow-up, in managing this rare type of LCH.

Xeroderma pigmentosum is a autosomal recessive genetic disorder in which cutaneous malignancies are very common. We report a rare case where four different varieties of cutaneous malignancies were seen in the same patient..

Carcinoma occurring in the cutaneous lesions of Lichen Planus though rarely mentioned in literature does occur and should be kept in mind while treating such lesions. We report a 16 year female who developed a squamous cell carcinoma in a long standing verrucous lichen planus in the lower leg. This case is being presented to indicate the possibility of malignant transformation of cutaneous lichen planus to carcinoma, especially in the hypertrophic forms and the need to have an early diagnosis so that it can be treated in the initial stages. A high degree of suspicion should be present whenever we come across a non healing lesion in a patient with lichen planus. A few markers, which may give us a clue for increased chances of malignant transformation in these cases is presented.
