“…Coelenterates (jellyfish or coral) usually bring about acute toxic reaction by toxic substances contained in nematocysts. It has been reported that delayed reactions to coelenterates can occur after the acute toxic reaction 22–26 . The histopathological features of the delayed reactions to the coelenterates are reported to usually show dense perivascular infiltrates composed primarily of lymphocytes and occasionally some histiocytes in the dermis 22–26 .…”

The histopathological features of the delayed reactions to the coelenterates are reported to usually show dense perivascular infiltrates composed primarily of lymphocytes and occasionally some histiocytes in the dermis 22–26 . These delayed reactions, however, are reported to sometimes cause a granulomatous dermatitis such as a tuberculoid‐type granuloma 8,9 .…”

Adequate clinical data and a sufficient workup, in addition to the histopathological findings, are frequently required to make a correct diagnosis of granulomatous dermatitis/panniculitis. These lesions with an unexpected etiology may include delayed hypersensitivity granulomatous reactions to various factors, such as metals or marine animal injuries. A 50-year-old male presented with multiple subcutaneous nodules on his right forearm 1 month following an octopus bite at his right wrist. After the disappearance of these lesions, which responded well to low-dose oral prednisone, another type of skin lesion characterized by small, numerous papules reappeared on his right forearm. Histopathologically, a specimen from a subcutaneous nodule showed mostly lobular granulomatous panniculitis, which showed an extensive diffuse infiltrate composed of numerous multinucleated giant cells and epithelioid cells intermingling with lymphocytes and eosinophils. A specimen from a papule that subsequently developed disclosed a diffuse granulomatous dermatitis composed of similar cells and also showed granuloma annulare-like features. This case is considered to be a delayed reaction after an octopus bite showing an unusual giant cell-rich granulomatous dermatitis/panniculitis. Octopus bites should therefore be included among the marine animal injuries, which cause a delayed-type reaction with granulomatous dermatitis/panniculitis.

“…In that report, the shiny and lichenoid coalescent papules with severe itching developed 3 weeks later after injuries which occurred to people who had a history of seafood allergy, atopic dermatitis, or previous contact with coelenterates 6,7 . The delayed reactions to cnidarians stings are not uncommon and may occur 2∼14 days after the occurrence of a sting injury 2,8 . It usually presents as a erythematous papular or papulonodular eruption with severe itching at the same site of the stings 2 .…”

“…It usually presents as a erythematous papular or papulonodular eruption with severe itching at the same site of the stings 2 . It takes several weeks to heal and may respond to topical or systemic steroids in combination with antihistamines 2,8 . Injuries that occur in the marine environment can be also infected with marine organisms such as Streptococcus species, Escherichia coli, Pseudomonas aeruginosa, Mycobacterium marinum, Staphylococcus aureus, Vibrio cholerae, Vibrio vulnificus, or Vibrio parahaemolyticus which are the most common pathogens isolated from seawater and marine wounds 3 .…”
