CPTCL-CP, cutaneous peripheral T-cell lymphoma of cytotoxic phenotype; ENK/TCL, extranodal natural killer/T-cell lymphoma; Ref, reference; yo, year old

Patients	Tumor	Comments	Ref
14 of 50 patients	Mycosis fungoides	In a study of 50 patients with primary and recurrent mycosis fungoides, 14 had either erythroderma and/or ulcerated lesions, on initial presentation; some of the patients with ulcerated lesions might be compatible with spontaneous (idiopathic) cutaneous tumor lysis syndrome	[27]
65 yo man	Mycosis fungoides	Necrotizing mycosis fungoides in a therapy-naive man may also represent spontaneous (idiopathic) cutaneous lysis syndrome	[28]
51 yo man	ENK/TCL, nasal type	ENK/TCL, nasal type presented in a previously healthy man with possible spontaneous (idiopathic) cutaneous tumor lysis syndrome as painless, ulcerated cutaneous lesions over his trunk and limbs	[29]
55 yo man	CPTCL-CP	CPTCL-CP presented with possible spontaneous (idiopathic) cutaneous tumor lysis syndrome-type characteristics as an ulcerated 5-cm cutaneous plaque on a man’s left ankle. During the subsequent month, nine additional, similar appearing, ulcerated plaques developed on his trunk and bilateral extremities	[30]
